- Add New Users
- </title><para>
- The Qpid Java Broker has a single reference source (<xref linkend="qpid_PrincipalDatabase"/>) that
- defines all the users in the system.
- </para><para>
- To add a new user to the broker the password file must be
- updated. The details about adding entries and when these updates
- take effect are dependent on the file format each of which are
- described below.

- Available
- Password file formats
- </title>
- <para>
- There are currently two different file formats available for use
- depending on the PrincipalDatabase that is desired. In all cases
- the clients need not be aware of the type of PrincipalDatabase in
- use they only need support the SASL mechanisms they provide.

- Plain

- <para>
- The plain file has the following format:
- </para>
- <programlisting>
-# Plain password authentication file.
-# default name : passwd
-# Format &lt;username&gt;:&lt;password&gt;
-#e.g.
-martin:password
-</programlisting>
- <para>
- As the contents of the file are plain text and the password is
- taken to be everything to the right of the ':'(colon). The
- password, therefore, cannot contain a ':' colon, but this can be
- used to delimit the password.
- </para><para>
- Lines starting with a '#' are treated as comments.

- config.xml file).
- </para><para>
- If you wish to use Base64 encoding for your password file, then
- in the &lt;class&gt; element above you should specify
- org.apache.qpid.server.security.auth.database.Base64MD5PasswordFilePrincipalDatabase

- Base64MD5
- Password File Format
- </title>
- <para>
- This format can be used to ensure that SAs cannot read the plain
- text password values from your password file on disk.
- </para><para>
- The Base64MD5 file uses the following format:
- </para>
- <programlisting>
-# Base64MD5 password authentication file
-# default name : qpid.passwd
-# Format &lt;username&gt;:&lt;Base64 Encoded MD5 hash of the users password&gt;
-#e.g.
-martin:X03MO1qnZdYdgyfeuILPmQ==
-</programlisting>
- <para>
- As with the Plain format the line is delimited by a ':'(colon).
- The password field contains the MD5 Hash of the users password
- encoded in Base64.
- </para><para>
- This file is read on broker start-up and is not re-read.

- <para>
- To update the file there are two options:
- </para><orderedlist>
- <listitem><para>Edit the file by hand using the <emphasis>qpid-passwd</emphasis> tool
- that will generate the required lines. The output from the tool
- is the text that needs to be copied in to your active password
- file. This tool is located in the broker bin directory.
- Eventually it is planned for this tool to emulate the
- functionality of <xref linkend="qpid_htpasswd"/>
- for qpid passwd files.
- <emphasis>NOTE:</emphasis> For the changes to be seen by the broker you must
- either restart the broker or reload the data with the
- management tools (see <xref linkend="Qpid-JMX-Management-Console-User-Guide"/>)
- </para></listitem>
- <listitem><para>Use the management tools to create a new user. The changes

- <para>
- The Plain password file and the Base64MD5 format file are both
- only read once on start up.
- </para><para>
- To make changes dynamically there are two options, both require
- administrator access via the Management Console (see <xref linkend="Qpid-JMX-Management-Console-User-Guide"/>)

- How password files and PrincipalDatabases relate to
- authentication mechanisms
- </title>
- <para>
- For each type of password file a PrincipalDatabase exists that
- parses the contents. These PrincipalDatabases load various SASL
- mechanism based on their supportability. e.g. the Base64MD5 file
- format can't support Plain authentication as the plain password
- is not available. Any client connecting need only be concerned
- about the SASL module they support and not the type of
- PrincipalDatabase. So I client that understands CRAM-MD5 will
- work correctly with a Plain and Base64MD5 PrincipalDatabase.
