 In order to enable Shibboleth support in gitlab we need to use Apache instead of Nginx (It may be possible to use Nginx, however this is difficult to configure using the bundled Nginx provided in the omnibus-gitlab package). Apache uses mod_shib2 module for shibboleth authentication and can pass attributes as headers to omniauth-shibboleth provider.
 
-
-To enable the Shibboleth OmniAuth provider you must:
-
-1. Configure Apache shibboleth module. Installation and configuration of module it self is out of scope of this document.
-Check https://wiki.shibboleth.net/ for more info.
-
-1. You can find Apache config in gitlab-recipes (https://gitlab.com/gitlab-org/gitlab-recipes/tree/master/web-server/apache)
-
-Following changes are needed to enable shibboleth:
-
-protect omniauth-shibboleth callback URL:
-```
-  <Location /users/auth/shibboleth/callback>
-    AuthType shibboleth
-    ShibRequestSetting requireSession 1
-    ShibUseHeaders On
-    require valid-user
-  </Location>
-
-  Alias /shibboleth-sp /usr/share/shibboleth
-  <Location /shibboleth-sp>
-    Satisfy any
-  </Location>
-
-  <Location /Shibboleth.sso>
-    SetHandler shib
-  </Location>
-```
-exclude shibboleth URLs from rewriting, add "RewriteCond %{REQUEST_URI} !/Shibboleth.sso" and "RewriteCond %{REQUEST_URI} !/shibboleth-sp", config should look like this:
-```
-  # Apache equivalent of Nginx try files
-  RewriteEngine on
-  RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
-  RewriteCond %{REQUEST_URI} !/Shibboleth.sso
-  RewriteCond %{REQUEST_URI} !/shibboleth-sp
-  RewriteRule .* http://127.0.0.1:8080%{REQUEST_URI} [P,QSA]
-  RequestHeader set X_FORWARDED_PROTO 'https'
-```
-
-1. Edit /etc/gitlab/gitlab.rb configuration file to enable OmniAuth and add
-Shibboleth as an OmniAuth provider. User attributes will be sent from the
-Apache reverse proxy to GitLab as headers with the names from the Shibboleth
-attribute mapping. Therefore the values of the `args` hash
-should be in the form of `"HTTP_ATTRIBUTE"`. The keys in the hash are arguments
-to the [OmniAuth::Strategies::Shibboleth class](https://github.com/toyokazu/omniauth-shibboleth/blob/master/lib/omniauth/strategies/shibboleth.rb)
-and are documented by the [omniauth-shibboleth gem](https://github.com/toyokazu/omniauth-shibboleth)
-(take care to note the version of the gem packaged with GitLab). If some of
-your users appear to be authenticated by Shibboleth and Apache, but GitLab
-rejects their account with a URI that contains "e-mail is invalid" then your
-Shibboleth Identity Provider or Attribute Authority may be asserting multiple
-e-mail addresses. In this instance, you might consider setting the
-`multi_values` argument to `first`.
-
-File should look like this:
-```
-external_url 'https://gitlab.example.com'
-gitlab_rails['internal_api_url'] = 'https://gitlab.example.com'
-
-# disable Nginx
-nginx['enable'] = false
-
-gitlab_rails['omniauth_allow_single_sign_on'] = true
-gitlab_rails['omniauth_block_auto_created_users'] = false
-gitlab_rails['omniauth_enabled'] = true
-gitlab_rails['omniauth_providers'] = [

You will be redirected to IdP server (Depends on your Shibboleth module configuration). If everything goes well the user will be returned to GitLab and will be signed in.
