<title>Using LDAP as authentication backend (optional)</title>
<para>
Instead of using Hydra's built-in user management you can optionally use LDAP to manage roles and users.
</para>
<para>
The <command>hydra-server</command> accepts the environment
variable <emphasis>HYDRA_LDAP_CONFIG</emphasis>. The value of
the variable should point to a valid YAML file containing the
Catalyst LDAP configuration. The format of the configuration
file is describe in the
<link xlink:href="https://metacpan.org/pod/Catalyst::Authentication::Store::LDAP#CONFIGURATION-OPTIONS">
<emphasis>Catalyst::Authentication::Store::LDAP</emphasis> documentation</link>.
An example is given below.
</para>
<para>
Roles can be assigned to users based on their LDAP group membership
(<emphasis>use_roles: 1</emphasis> in the below example).
For a user to have the role <emphasis>admin</emphasis> assigned to them
they should be in the group <emphasis>hydra_admin</emphasis>. In general
any LDAP group of the form <emphasis>hydra_some_role</emphasis>
(notice the <emphasis>hydra_</emphasis> prefix) will work.
