 ## Workflow labels
 
-Labelling issues is described in the [GitLab Inc engineering workflow].
+To allow for asynchronous issue handling, we use [milestones][milestones-page]
+and [labels][labels-page]. Leads and product managers handle most of the
+scheduling into milestones. Labelling is a task for everyone.
 
-## Implement design & UI elements
+Most issues will have labels for at least one of the following:
 
-Please see the [UX Guide for GitLab].
+- Type: ~"feature proposal", ~bug, ~customer, etc.
+- Subject: ~wiki, ~"container registry", ~ldap, ~api, etc.
+- Team: ~CI, ~Discussion, ~Edge, ~Frontend, ~Platform, etc.
+- Priority: ~Deliverable, ~Stretch
+
+All labels, their meaning and priority are defined on the
+[labels page][labels-page].
+
+If you come across an issue that has none of these, and you're allowed to set
+labels, you can _always_ add the team and type, and often also the subject.
+
+[milestones-page]: https://gitlab.com/gitlab-org/gitlab-ce/milestones
+[labels-page]: https://gitlab.com/gitlab-org/gitlab-ce/labels
+
+### Type labels (~"feature proposal", ~bug, ~customer, etc.)
+
+Type labels are very important. They define what kind of issue this is. Every
+issue should have one or more.
+
+Examples of type labels are ~"feature proposal", ~bug, ~customer, ~security,
+and ~"direction".
+
+A number of type labels have a priority assigned to them, which automatically
+makes them float to the top, depending on their importance.
+
+Type labels are always lowercase, and can have any color, besides blue (which is
+already reserved for subject labels).
+
+The descriptions on the [labels page][labels-page] explain what falls under each type label.
+
+### Subject labels (~wiki, ~"container registry", ~ldap, ~api, etc.)
+
+Subject labels are labels that define what area or feature of GitLab this issue
+hits. They are not always necessary, but very convenient.
+
+If you are an expert in a particular area, it makes it easier to find issues to
+work on. You can also subscribe to those labels to receive an email each time an
+issue is labelled with a subject label corresponding to your expertise.
+
+Examples of subject labels are ~wiki, ~"container registry", ~ldap, ~api,
+~issues, ~"merge requests", ~labels, and ~"container registry".
+
+Subject labels are always all-lowercase.
+
+### Team labels (~CI, ~Discussion, ~Edge, ~Platform, etc.)
+
+Team labels specify what team is responsible for this issue.
+Assigning a team label makes sure issues get the attention of the appropriate
+people.
+
+The current team labels are ~Build, ~CI, ~Discussion, ~Documentation, ~Edge,
+~Gitaly, ~Platform, ~Prometheus, ~Release, and ~"UX".
+
+The descriptions on the [labels page][labels-page] explain what falls under the
+responsibility of each team.
+
+Within those team labels, we also have the ~backend and ~frontend labels to
+indicate if an issue needs backend work, frontend work, or both.
+
+Team labels are always capitalized so that they show up as the first label for
+any issue.
 
-## Release retrospective and kickoff
+### Priority labels (~Deliverable and ~Stretch)
 
-### Retrospective
+Priority labels help us clearly communicate expectations of the work for the
+release. There are two levels of priority labels:
 
-After each release, we have a retrospective call where we discuss what went well,
-what went wrong, and what we can improve for the next release. The
-[retrospective notes] are public and you are invited to comment on them.
-If you're interested, you can even join the
-[retrospective call][retro-kickoff-call], on the first working day after the
-22nd at 6pm CET / 9am PST.
+- ~Deliverable: Issues that are expected to be delivered in the current
+  milestone.
+- ~Stretch: Issues that are a stretch goal for delivering in the current
+  milestone. If these issues are not done in the current release, they will
+  strongly be considered for the next release.
 
-### Kickoff
+### Label for community contributors (~"Accepting Merge Requests")
 
-Before working on the next release, we have a
-kickoff call to explain what we expect to ship in the next release. The
-[kickoff notes] are public and you are invited to comment on them.
-If you're interested, you can even join the [kickoff call][retro-kickoff-call],
-on the first working day after the 7th at 6pm CET / 9am PST..
+Issues that are beneficial to our users, 'nice to haves', that we currently do
+not have the capacity for or want to give the priority to, are labeled as
+~"Accepting Merge Requests", so the community can make a contribution.

+Community contributors can submit merge requests for any issue they want, but
+the ~"Accepting Merge Requests" label has a special meaning. It points to
+changes that:
+
+1. We already agreed on,
+1. Are well-defined,
+1. Are likely to get accepted by a maintainer.
+
+We want to avoid a situation when a contributor picks an
+~"Accepting Merge Requests" issue and then their merge request gets closed,
+because we realize that it does not fit our vision, or we want to solve it in a
+different way.
+
+We add the ~"Accepting Merge Requests" label to:
+
+- Low priority ~bug issues (i.e. we do not add it to the bugs that we want to
+solve in the ~"Next Patch Release")
+- Small ~"feature proposal" that do not need ~UX / ~"Product work", or for which
+the ~UX / ~"Product work" is already done
+- Small ~"technical debt" issues
+
+After adding the ~"Accepting Merge Requests" label, we try to estimate the
+[weight](#issue-weight) of the issue. We use issue weight to let contributors
+know how difficult the issue is. Additionally:
+
+- We advertise [~"Accepting Merge Requests" issues with weight < 5][up-for-grabs]
+  as suitable for people that have never contributed to GitLab before on the
+  [Up For Grabs campaign](http://up-for-grabs.net)
+- We encourage people that have never contributed to any open source project to
+  look for [~"Accepting Merge Requests" issues with a weight of 1][firt-timers]

 ## Common actions
 
-### Issue triaging
-
-Our issue triage policies are [described in our handbook]. You are very welcome
-to help the GitLab team triage issues. We also organize [issue bash events] once
-every quarter.
-
-The most important thing is making sure valid issues receive feedback from the
-development team. Therefore the priority is mentioning developers that can help
-on those issues. Please select someone with relevant experience from
-[GitLab team][team]. If there is nobody mentioned with that expertise
-look in the commit history for the affected files to find someone. Avoid
-mentioning the lead developer, this is the person that is least likely to give a
-timely response. If the involvement of the lead developer is needed the other
-core team members will mention this person.

 ## Assigning issues
 
 If an issue is complex and needs the attention of a specific person, assignment is a good option but assigning issues might discourage other people from contributing to that issue. We need all the contributions we can get so this should never be discouraged. Also, an assigned person might not have time for a few weeks, so others should feel free to takeover.

+### Retrospective
+
+After each release, we have a retrospective call where we discuss what went well,
+what went wrong, and what we can improve for the next release. The
+[retrospective notes] are public and you are invited to comment on them.
+If you're interested, you can even join the
+[retrospective call][retro-kickoff-call], on the first working day after the
+22nd at 6pm CET / 9am PST.

+### Kickoff
+
+Before working on the next release, we have a
+kickoff call to explain what we expect to ship in the next release. The
+[kickoff notes] are public and you are invited to comment on them.

+# Serializers
+
+This is a documentation for classes located in `app/serializers` directory.
+
+In GitLab, we use [grape-entities][grape-entity-project], accompanied by a
+serializer, to convert a Ruby object to its JSON representation.
+
+Serializers are typically used in controllers to build a JSON response
+that is usually consumed by a frontend code.
+
+## Why using a serializer is important?
+
+Using serializers, instead of `to_json` method, has several benefits:
+
+* it helps to prevent exposure of a sensitive data stored in the database
+* it makes it easier to test what should and should not be exposed
+* it makes it easier to reuse serialization entities that are building blocks
+* it makes it easier to move complexity from controllers to easily testable
+  classes
+* it encourages hiding complexity behind intentions-revealing interfaces
+* it makes it easier to take care about serialization performance concerns
+* it makes it easier to reduce merge conflicts between CE -> EE
+* it makes it easier to benefit from domain driven development techniques
+
+## What is a serializer?
+
+A serializer is a class that encapsulates all business rules for building a
+JSON response using serialization entities.
+
+It is designed to be testable and to support passing additional context from
+the controller.
+
+## What is a serialization entity?
+
+Entities are lightweight structures that allow to represent domain models
+in a consistent and abstracted way, and reuse them as building blocks to
+create a payload.
+
+Entities located in `app/serializers` are usually derived from a
+[`Grape::Entity`][grape-entity-class] class.
+
+Serialization entities that do require to have a knowledge about specific
+elements of the request, need to mix `RequestAwareEntity` in.
+
+A serialization entity usually maps a domain model class into its JSON
+representation. It rarely happens that a serialization entity exists without
+a corresponding domain model class. As an example, we have an `Issue` class and
+a corresponding `IssueSerializer`.
+
+Serialization entites are designed to reuse other serialization entities, which
+is a convenient way to create a multi-level JSON representation of a piece of
+a domain model you want to serialize.
+
+See [documentation for Grape Entites][grape-entity-readme] for more details.
+
+## How to implement a serializer?
+
+### Base implementation
+
+In order to effectively implement a serializer it is necessary to create a new
+class in `app/serializers`. See existing serializers as an example.
+
+A new serializer should inherit from a `BaseSerializer` class. It is necessary
+to specify which serialization entity will be used to serialize a resource.
+
+```ruby
+class MyResourceSerializer < BaseSerialize
+  entity MyResourceEntity
+end
+```
+
+The example above shows how a most simple serializer can look like.
+
+Given that the entity `MyResourceEntity` exists, you can now use
+`MyResourceSerializer` in the controller by creating an instance of it, and
+calling `MyResourceSerializer#represent(resource)` method.
+
+Note that a `resource` can be either a single object, an array of objects or an
+`ActiveRecord::Relation` object. A serialization entity should be smart enough
+to accurately represent each of these.
+
+It should not be necessary to use `Enumerable#map`, and it should be avoided
+from the performance reasons.
+
+### Choosing what gets serialized
+
+It often happens that you might want to use the same serializer in many places,
+but sometimes the intention is to only expose a small subset of object's
+attributes in one place, and a different subset in another.
+
+`BaseSerializer#represent(resource, opts = {})` method can take an additional
+hash argument, `opts`, that defines what is going to be serialized.
+
+`BaseSerializer` will pass these options to a serialization entity. See
+how it is [documented in the upstream project][grape-entity-only].
+
+With this approach you can extend the serializer to respond to methods that will
+create a JSON response according to your needs.
+
+```ruby
+class PipelineSerializer < BaseSerializer
+  entity PipelineEntity
+
+  def represent_details(resource)
+    represent(resource, only: [:details])
+  end
+
+  def represent_status(resource)
+    represent(resource, only: [:status])
+  end
+end
+```
+
+It is possible to use `only` and `except` keywords. Both keywords do support
+nested attributes, like `except: [:id, { user: [:id] }]`.
+
+Passing `only` and `except` to the `represent` method from a controller is
+possible, but it defies principles of encapsulation and testability, and it is
+better to avoid it, and to add a specific method to the serializer instead.
+
+### Reusing serialization entities from the API
+
+Public API in GitLab is implemented using [Grape][grape-project].
+
+Under the hood it also uses [`Grape::Entity`][grape-entity-class] classes.
+This means that it is possible to reuse these classes to implement internal
+serializers.
+
+You can either use such entity directly:
+
+```ruby
+class MyResourceSerializer < BaseSerializer
+  entity API::Entities::SomeEntity
+end
+```
+
+Or derive a new serialization entity class from it:
+
+```ruby
+class MyEntity < API::Entities::SomeEntity
+  include RequestAwareEntity
+
+  unexpose :something
+end
+```
+
+It might be a good idea to write specs for entities that do inherit from
+the API, because when API payloads are changed / extended, it is easy to forget
+about the impact on the internal API through a serializer that reuses API
+entities.
+
+It is usually safe to do that, because API entities rarely break backward
+compatibility, but additional exposure may have a performance impact when API
+gets extended significantly. Write tests that check if only necessary data is
+exposed.
+
+## How to write tests for a serializer?
+
+Like every other class in the project, creating a serializer warrants writing
+tests for it.
+
+It is usually a good idea to test each public method in the serializer against
+a valid payload. `BaseSerializer#represent` returns a hash, so it is possible
+to use usual RSpec matchers like `include`.
+
+Sometimes, when the payload is large, it makes sense to validate it entirely
+using `match_response_schema` matcher along with a new fixture that can be
+stored in `spec/fixtures/api/schemas/`. This matcher is using a `json-schema`
+gem, which is quite flexible, see a [documentation][json-schema-gem] for it.
+
+## How to use a serializer in a controller?
+
+Once a new serializer is implemented, it is possible to use it in a controller.
+
+Create an instance of the serializer and render the response.
+
+```ruby
+def index
+  format.json do
+    render json: MyResourceSerializer
+      .new(current_user: @current_user)
+      .represent_details(@project.resources)
+  nd
+end
+```
+
+If it is necessary to include additional information in the payload, it is
+possible to extend what is going to be rendered, the usual way:
+
+```ruby
+def index
+  format.json do
+    render json: {
+      resources: MyResourceSerializer
+        .new(current_user: @current_user)
+        .represent_details(@project.resources),
+      count: @project.resources.count
+    }
+  nd
+end
+```
+
+Note that in these examples an additional context is being passed to the
+serializer (`current_user: @current_user`).
+
+## How to pass an additional context from the controller?
+
+It is possible to pass an additional context from a controller to a
+serializer and each serialization entity that is used in the process.
+
+Serialization entities that do require an additional context have
+`RequestAwareEntity` concern mixed in. This piece of the code exposes a method
+called `request` in every serialization entity that is instantiated during
+serialization.
+
+An object returned by this method is an instance of `EntityRequest`, which
+behaves like an `OpenStruct` object, with the difference that it will raise
+an error if an unknown method is called.
+
+In other words, in the previous example, `request` method will return an
+instance of `EntityRequest` that responds to `current_user` method. It will be
+available in every serialization entity instantiated by `MyResourceSerializer`.
+
+`EntityRequest` is a workaround for [#20045][issue-20045] and is meant to be
+refactored soon. Please avoid passing an additional context that is not
+required by a serialization entity.
+
+At the moment, the context that is passed to entities most often is
+`current_user` and `project`.
+
+## How is this related to using presenters?
+
+Payload created by a serializer is usually a representation of the backed code,
+combined with the current request data. Therefore, technically, serializers
+are presenters that create payload consumed by a frontend code, usually Vue
+components.
+
+In GitLab, it is possible to use [presenters][presenters-readme], but
+`BaseSerializer` still needs to learn how to use it, see [#30898][issue-30898].
+
+It is possible to use presenters when serializer is used to represent only
+a single object. It is not supported when  `ActiveRecord::Relation` is being
+serialized.
+
+```ruby
+MyObjectSerializer.new.represent(object.present)
+```
+
+## Best practices
+
+1. Do not invoke a serializer from within a serialization entity.
+
+    If you need to use a serializer from within a serialization entity, it is
+    possible that you are missing a class for an important domain concept.
+
+    Consider creating a new domain class and a corresponding serialization
+    entity for it.
+
+1. Use only one approach to switch behavior of the serializer.
+
+    It is possible to use a few approaches to switch a behavior of the
+    serializer. Most common are using a [Fluent Interface][fluent-interface]
+    and creating a separate `represent_something` methods.
+
+    Whatever you choose, it might be better to use only one approach at a time.
+
+1. Do not forget about creating specs for serialization entities.
+
+    Writing tests for the serializer indeed does cover testing a behavior of
+    serialization entities that the serializer instantiates. However it might
+    be a good idea to write separate tests for entities as well, because these
+    are meant to be reused in different serializers, and a serializer can
+    change a behavior of a serialization entity.
+
+1. Use `ActiveRecord::Relation` where possible
+
+    Using an `ActiveRecord::Relation` might help from the performance perspective.
+
+1. Be diligent about passing an additional context from the controller.
+
+    Using `EntityRequest` and `RequestAwareEntity` is a workaround for the lack
+    of high-level mechanism. It is meant to be refactored, and current
+    implementation is error prone. Imagine the situation that one serialization
+    entity requires `request.user` attribute, but the second one wants
+    `request.current_user`. When it happens that these two entities are used in
+    the same serialization request, you might need to pass both parameters to
+    the serializer, which is obviously not a perfect situation.
+
+    When in doubt, pass only `current_user` and `project` if these are required.
+
+1. Keep performance concerns in mind
+
+    Using a serializer incorrectly can have significant impact on the
+    performance.
+
+    Because serializers are technically presenters, it is often necessary
+    to calculate, for example, paths to various controller-actions.
+    Since using URL helpers usually involve passing `project` and `namespace`
+    adding `includes(project: :namespace)` in the serializer, can help to avoid
+    N+1 queries.
+
+    Also, try to avoid using `Enumerable#map` or other methods that will
+    execute a database query eagerly.
+
+1. Avoid passing `only` and `except` from the controller.
+1. Write tests checking for N+1 queries.
+1. Write controller tests for actions / formats using serializers.
+1. Write tests that check if only necessary data is exposed.
+1. Write tests that check if no sensitive data is exposed.

+# How to configure LDAP with GitLab CE
+
+> **Type:** admin guide ||
+> **Level:** intermediary ||
+> **Author:** [Chris Wilson](https://gitlab.com/MrChrisW) ||
+> **Publication date:** 2017/05/03
+
+## Introduction
+
+Managing a large number of users in GitLab can become a burden for system administrators. As an organization grows so do user accounts. Keeping these user accounts in sync across multiple enterprise applications often becomes a time consuming task.
+
+In this guide we will focus on configuring GitLab with Active Directory. [Active Directory](https://en.wikipedia.org/wiki/Active_Directory) is a popular LDAP compatible directory service provided by Microsoft, included in all modern Windows Server operating systems.
+
+GitLab has supported LDAP integration since [version 2.2](https://about.gitlab.com/2012/02/22/gitlab-version-2-2/). With GitLab LDAP [group syncing](#group-syncing-ee) being added to GitLab Enterprise Edition in [version 6.0](https://about.gitlab.com/2013/08/20/gitlab-6-dot-0-released/). LDAP integration has become one of the most popular features in GitLab.
+
+## Getting started
+
+### Choosing an LDAP Server
+
+The main reason organizations choose to utilize a LDAP server is to keep the entire organization's user base consolidated into a central repository. Users can access multiple applications and systems across the  IT environment using a single login. Because LDAP is an open, vendor-neutral, industry standard application protocol, the number of applications using LDAP authentication continues to increase.
+
+There are many commercial and open source [directory servers](https://en.wikipedia.org/wiki/Directory_service#LDAP_implementations) that support the LDAP protocol. Deciding on the right directory server highly depends on the existing IT environment in which the server will be integrated with.
+
+For example, [Active Directory](https://technet.microsoft.com/en-us/library/hh831484(v=ws.11).aspx) is generally favored in a primarily Windows environment, as this allows quick integration with existing services. Other popular directory services include:
+
+- [Oracle Internet Directory](http://www.oracle.com/technetwork/middleware/id-mgmt/overview/index-082035.html)
+- [OpenLDAP](http://www.openldap.org/)
+- [389 Directory](http://directory.fedoraproject.org/)
+- [OpenDJ](https://forgerock.org/opendj/)
+- [ApacheDS](https://directory.apache.org/)
+
+> GitLab uses the [Net::LDAP](https://rubygems.org/gems/net-ldap) library under the hood. This means it supports all [IETF](https://tools.ietf.org/html/rfc2251) compliant LDAPv3 servers.
+
+### Active Directory (AD)
+
+We won't cover the installation and configuration of Windows Server or Active Directory Domain Services in this tutorial. There are a number of resources online to guide you through this process:
+
+- Install Windows Server 2012  - (_technet.microsoft.com_) - [Installing Windows Server 2012 ](https://technet.microsoft.com/en-us/library/jj134246(v=ws.11).aspx)
+
+- Install Active Directory Domain Services (AD DS) (_technet.microsoft.com_)- [Install Active Directory Domain Services](https://technet.microsoft.com/windows-server-docs/identity/ad-ds/deploy/install-active-directory-domain-services--level-100-#BKMK_PS)
+
+> **Shortcut:** You can quickly install AD DS via PowerShell using
+`Install-WindowsFeature AD-Domain-Services -IncludeManagementTools`
+
+### Creating an AD **OU** structure
+
+Configuring organizational units (**OU**s) is an important part of setting up Active Directory. **OU**s form the base for an entire organizational structure. Using GitLab as an example we have designed the **OU** structure below using the geographic **OU** model. In the Geographic Model we separate **OU**s for different geographic regions.
+
+| GitLab **OU** Design           |  GitLab AD Structure             |
+| :----------------------------: | :------------------------------: |
+| ![GitLab OU Design][gitlab_ou] |  ![GitLab AD Structure][ldap_ou] |
+
+[gitlab_ou]: img/gitlab_ou.png
+[ldap_ou]: img/ldap_ou.gif
+
+Using PowerShell you can output the **OU** structure as a table (_all names are examples only_):
+
+```ps
+Get-ADObject -LDAPFilter "(objectClass=*)" -SearchBase 'OU=GitLab INT,DC=GitLab,DC=org' -Properties CanonicalName | Format-Table Name,CanonicalName -A
+```
+
+```

+
+## GitLab LDAP configuration
+
+The initial configuration of LDAP in GitLab requires changes to the `gitlab.rb` configuration file. Below is an example of a complete configuration using an Active Directory.
+
+The two Active Directory specific values are `active_directory: true` and `uid: 'sAMAccountName'`. `sAMAccountName` is an attribute returned by Active Directory used for GitLab usernames. See the example output from `ldapsearch` for a full list of attributes a "person" object (user) has in **AD** - [`ldapsearch` example](#using-ldapsearch-unix)
+
+> Both group_base and admin_group configuration options are only available in GitLab Enterprise Edition. See [GitLab EE - LDAP Features](#gitlab-enterprise-edition---ldap-features)
+
+### Example `gitlab.rb` LDAP
+
+```
+gitlab_rails['ldap_enabled'] = true
+gitlab_rails['ldap_servers'] = {
+'main' => {
+  'label' => 'GitLab AD',
+  'host' =>  'ad.example.org',
+  'port' => 636,
+  'uid' => 'sAMAccountName',
+  'method' => 'ssl',
+  'bind_dn' => 'CN=GitLabSRV,CN=Users,DC=GitLab,DC=org',
+  'password' => 'Password1',
+  'active_directory' => true,
+  'base' => 'OU=GitLab INT,DC=GitLab,DC=org',
+  'group_base' => 'OU=Global Groups,OU=GitLab INT,DC=GitLab,DC=org',
+  'admin_group' => 'Global Admins'
+  }
+}
+```
+
+> **Note:** Remember to run  `gitlab-ctl reconfigure` after modifying `gitlab.rb`
+
+## Security improvements (LDAPS)
+
+Security is an important aspect when deploying an LDAP server. By default, LDAP traffic is transmitted unsecured. LDAP can be secured using SSL/TLS called LDAPS, or commonly "LDAP over SSL".
+
+Securing LDAP (enabling LDAPS) on Windows Server 2012 involves installing a valid SSL certificate. For full details see Microsoft's guide [How to enable LDAP over SSL with a third-party certification authority](https://support.microsoft.com/en-us/help/321051/how-to-enable-ldap-over-ssl-with-a-third-party-certification-authority)
+
+> By default a LDAP service listens for connections on TCP and UDP port 389. LDAPS (LDAP over SSL) listens on port 636
+
+### Testing you AD server
+
+#### Using **AdFind** (Windows)
+
+You can use the [`AdFind`](https://social.technet.microsoft.com/wiki/contents/articles/7535.adfind-command-examples.aspx) utility (on Windows based systems) to test that your LDAP server is accessible and authentication is working correctly. This is a freeware utility built by [Joe Richards](http://www.joeware.net/freetools/tools/adfind/index.htm).
+
+**Return all objects**
+
+You can use the filter `objectclass=*` to return all directory objects.
+
+```sh
+adfind -h ad.example.org:636 -ssl -u "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -up Password1 -b "OU=GitLab INT,DC=GitLab,DC=org" -f (objectClass=*)
+```
+
+**Return single object using filter**
+
+You can also retrieve a single object by **specifying** the object name or full **DN**. In this example we specify the object name only `CN=Leroy Fox`.
+
+```sh
+adfind -h ad.example.org:636 -ssl -u "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -up Password1 -b "OU=GitLab INT,DC=GitLab,DC=org" -f (&(objectcategory=person)(CN=Leroy Fox))”
+```
+
+#### Using **ldapsearch** (Unix)
+
+You can use the `ldapsearch` utility (on Unix based systems) to test that your LDAP server is accessible and authentication is working correctly. This utility is included in the [`ldap-utils`](https://wiki.debian.org/LDAP/LDAPUtils) package.
+
+**Return all objects**
+
+You can use the filter `objectclass=*` to return all directory objects.
+
+```sh
+ldapsearch -D "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" \
+-w Password1 -p 636 -h ad.example.org \
+-b "OU=GitLab INT,DC=GitLab,DC=org" -Z \
+-s sub "(objectclass=*)"
+```
+
+**Return single object using filter**
+
+You can also retrieve a single object by **specifying** the object name or full **DN**. In this example we specify the object name only `CN=Leroy Fox`.
+
+```sh
+ldapsearch -D "CN=GitLabSRV,CN=Users,DC=GitLab,DC=org" -w Password1 -p 389 -h ad.example.org -b "OU=GitLab INT,DC=GitLab,DC=org" -Z -s sub "CN=Leroy Fox"
+```
+
+**Full output of `ldapsearch` command:** - Filtering for _CN=Leroy Fox_
+
+```
+# LDAPv3
+# base <OU=GitLab INT,DC=GitLab,DC=org> with scope subtree
+# filter: CN=Leroy Fox

+
+## Basic user authentication
+
+After configuring LDAP, basic authentication will be available. Users can then login using their directory credentials. An extra tab is added to the GitLab login screen for the configured LDAP server (e.g "**GitLab AD**").
+
+![GitLab OU Structure](img/user_auth.gif)
+
+Users that are removed from the LDAP base group (e.g `OU=GitLab INT,DC=GitLab,DC=org`) will be **blocked** in GitLab. [More information](../../administration/auth/ldap.md#security) on LDAP security.
+
+If `allow_username_or_email_login` is enabled in the LDAP configuration, GitLab will ignore everything after the first '@' in the LDAP username used on login. Example: The username `jon.doe@example.com` is converted to `jon.doe` when authenticating with the LDAP server. Disable this setting if you use `userPrincipalName` as the `uid`.
+
+## LDAP extended features on GitLab EE
+
+With [GitLab Enterprise Edition (EE)](https://about.gitlab.com/giltab-ee/), besides everything we just described, you'll
+have extended functionalities with LDAP, such as:
+
+- Group sync
+- Group permissions
+- Updating user permissions
+- Multiple LDAP servers
+
+Read through the article on [LDAP for GitLab EE](https://docs.gitlab.com/ee/articles/how_to_configure_ldap_gitlab_ee/) for an overview.

+
+Pipelines can be complex structures with many sequential and parallel jobs.
+To make it a little easier to see what is going on, you can view a graph
+of a single pipeline and its status.
+
+A pipeline graph can be shown in two different ways depending on what page you

+
+The regular pipeline graph that shows the names of the jobs of each stage can
+be found when you are on a [single pipeline page](#seeing-pipeline-status).

+Then, there is the pipeline mini graph which takes less space and can give you a
+quick glance if all jobs pass or something failed. The pipeline mini graph can
+be found when you visit:
+
+- the pipelines index page
+- a single commit page
+- a merge request page
+
+That way, you can see all related jobs for a single commit and the net result
+of each stage of your pipeline. This allows you to quickly see what failed and
+fix it. Stages in pipeline mini graphs are collapsible. Hover your mouse over
+them and click to expand their jobs.

+If you have many similar jobs, your pipeline graph becomes very long and hard
+to read. For that reason, similar jobs can automatically be grouped together.
+If the job names are formatted in certain ways, they will be collapsed into
+a single group in regular pipeline graphs (not the mini graphs).
+You'll know when a pipeline has grouped jobs if you don't see the retry or
+cancel button inside them. Hovering over them will show the number of grouped
+jobs. Click to expand them.
+
+![Grouped pipelines](img/pipelines_grouped.png)
+
+The basic requirements is that there are two numbers separated with one of
+the following (you can even use them interchangeably):
+
+- a space
+- a backslash (`/`)
+- a colon (`:`)
+
+>**Note:**
+More specifically, [it uses][regexp] this regular expression: `\d+[\s:\/\\]+\d+\s*`.
+
+The jobs will be ordered by comparing those two numbers from left to right. You
+usually want the first to be the index and the second the total.
+
+For example, the following jobs will be grouped under a job named `test`:
+
+- `test 0 3` => `test`
+- `test 1 3` => `test`
+- `test 2 3` => `test`
+
+The following jobs will be grouped under a job named `test ruby`:
+
+- `test 1:2 ruby` => `test ruby`
+- `test 2:2 ruby` => `test ruby`
+
+The following jobs will be grouped under a job named `test ruby` as well:
+
+- `1/3 test ruby` => `test ruby`
+- `2/3 test ruby` => `test ruby`
+- `3/3 test ruby` => `test ruby`
+
+### Manual actions from the pipeline graph
+
+> [Introduced][ce-7931] in GitLab 8.15.
+
+[Manual actions][manual] allow you to require manual interaction before moving
+forward with a particular job in CI. Your entire pipeline can run automatically,
+but the actual [deploy to production][env-manual] will require a click.
+
+You can do this straight from the pipeline graph. Just click on the play button
+to execute that particular job. For example, in the image below, the `production`
+stage has a job with a manual action.

+
+**Regular pipeline graph**
+
+In the single pipeline page, jobs are sorted by name.
+
+**Mini pipeline graph**
+
+> [Introduced][ce-9760] in GitLab 9.0.
+
+In the pipeline mini graphs, the jobs are sorted first by severity and then
+by name. The order of severity is:
+
+- failed
+- warning
+- pending
+- running
+- manual
+- canceled
+- success
+- skipped
+- created

+# Building a package for testing
+
+While developing a new feature or modifying an existing one, it is helpful if an
+installable package (or a docker image) containing those changes is available
+for testing. For this very purpose, a manual job is provided in the GitLab CI/CD
+pipeline that can be used to trigger a pipeline in the omnibus-gitlab repository
+that will create
+1. A deb package for Ubuntu 16.04, available as a build artifact, and
+2. A docker image, which is pushed to [Omnibus GitLab's container 
+registry](https://gitlab.com/gitlab-org/omnibus-gitlab/container_registry)
+(images titled `gitlab-ce` and `gitlab-ee` respectively and image tag is the
+commit which triggered the pipeline).
+
+When you push a commit to either the gitlab-ce or gitlab-ee project, the
+pipeline for that commit will have a `build-package` manual action you can
+trigger.
+
+## Specifying versions of components
+
+If you want to create a package from a specific branch, commit or tag of any of
+the GitLab components (like GitLab Workhorse, Gitaly, GitLab Pages, etc.), you
+can specify the branch name, commit sha or tag in the component's respective
+`*_VERSION` file. For example, if you want to build a package that uses the
+branch `0-1-stable`, modify the content of `GITALY_SERVER_VERSION` to
+`0-1-stable` and push the commit. This will create a manual job that can be
+used to trigger the build.
+
+## Specifying the branch in omnibus-gitlab repository
+
+In scenarios where a configuration change is to be introduced and omnibus-gitlab
+repository already has the necessary changes in a specific branch, you can build
+a package against that branch through an environment variable named
+`OMNIBUS_BRANCH`. To do this, specify that environment variable with the name of
+the branch as value in `.gitlab-ci.yml` and push a commit. This will create a
+manual job that can be used to trigger the build.

 # Code Review Guidelines
 
+## Getting your merge request reviewed, approved, and merged
+
+There are a few rules to get your merge request accepted:
+
+1. Your merge request should only be **merged by a [maintainer][team]**.
+  1. If your merge request includes only backend changes [^1], it must be
+    **approved by a [backend maintainer][team]**.
+  1. If your merge request includes only frontend changes [^1], it must be
+    **approved by a [frontend maintainer][team]**.
+  1. If your merge request includes frontend and backend changes [^1], it must
+    be **approved by a [frontend and a backend maintainer][team]**.
+1. To lower the amount of merge requests maintainers need to review, you can
+  ask or assign any [reviewers][team] for a first review.
+  1. If you need some guidance (e.g. it's your first merge request), feel free
+    to ask one of the [Merge request coaches][team].
+  1. The reviewer will assign the merge request to a maintainer once the
+    reviewer is satisfied with the state of the merge request.

+The `path` column for these rows will be renamed to their previous value followed
+by an integer. For example: `users` would turn into `users0`

+# Wiki
+
+A separate system for documentation called Wiki, is built right into each
+GitLab project. It is enabled by default on all new projects and you can find
+it under **Wiki** in your project.
+
+Wikis are very convenient if you don't want to keep you documentation in your
+repository, but you do want to keep it in the same project where your code
+resides.
+
+You can create Wiki pages in the web interface or
+[locally using Git](#adding-and-editing-wiki-pages-locally) since every Wiki is
+a separate Git repository.
+
+>**Note:**
+A [permission level][permissions] of **Guest** is needed to view a Wiki and
+**Developer** is needed to create and edit Wiki pages.
+
+## First time creating the Home page
+
+The first time you visit a Wiki, you will be directed to create the Home page.
+The Home page is necessary to be created since it serves as the landing page
+when viewing a Wiki. You only have to fill in the **Content** section and click
+**Create page**. You can always edit it later, so go ahead and write a welcome
+message.

+will create the path to the page. You can specify a full path for the new file
+and any missing directories will be created automatically.
+
+![New page modal](img/wiki_create_new_page_modal.png)
+
+Once you enter the page name, it's time to fill in its content. GitLab wikis
+support Markdown, RDoc and AsciiDoc. For Markdown based pages, all the
+[Markdown features](../../markdown.md) are supported and for links there is
+some [wiki specific](../../markdown.md#wiki-specific-markdown) behavior.
+
+>**Note:**
+The wiki is based on a Git repository and contains only text files. Uploading
+files via the web interface will upload them in GitLab itself, and they will
+not be available if you clone the wiki repo locally.
+
+In the web interface the commit message is optional, but the GitLab Wiki is
+based on Git and needs a commit message, so one will be created for you if you
+do not enter one.
+
+When you're ready, click the **Create page** and the new page will be created.
+
+![New page](img/wiki_create_new_page.png)
+
+## Editing a wiki page
+
+To edit a page, simply click on the **Edit** button. From there on, you can
+change its content. When done, click **Save changes** for the changes to take
+effect.
+
+## Deleting a wiki page
+
+You can find the **Delete** button only when editing a page. Click on it and
+confirm you want the page to be deleted.
+
+## Viewing a list of all created wiki pages
+
+Every wiki has a sidebar from which a short list of the created pages can be
+found. The list is ordered alphabetically.
+
+![Wiki sidebar](img/wiki_sidebar.png)
+
+If you have many pages, not all will be listed in the sidebar. Click on
+**More pages** to see all of them.
+
+## Viewing the history of a wiki page
+
+The changes of a wiki page over time are recorded in the wiki's Git repository,
+and you can view them by clicking the **Page history** button.
+
+From the history page you can see the revision of the page (Git commit SHA), its
+author, the commit message, when it was last updated and the page markup format.
+To see how a previous version of the page looked like, click on a revision
+number.
+
+![Wiki page history](img/wiki_page_history.png)
+
+## Adding and editing wiki pages locally
+
+Since wikis are based on Git repositories, you can clone them locally and edit
+them like you would do with every other Git repository.
+
+On the right sidebar, click on **Clone repository** and follow the on-screen
+instructions.
