-      binddn: "cn=root,dc=example"

-        verify:  none
+    </credential>
-      user_basedn: "ou=users,dc=example"
+    <store>
-      user_filter: "(&(objectClass=inetOrgPerson)(cn=%s))"
+      class = LDAP
-      user_scope: one
+      ldap_server = localhost
-      user_field: cn
+      <ldap_server_options>
-      user_search_options:
+        timeout = 30
-        deref: always
+      </ldap_server_options>
-      use_roles: 1
+      binddn = "cn=root,dc=example"
-      role_basedn: "ou=groups,dc=example"
+      include ldap-password.conf
-      role_filter: "(&(objectClass=groupOfNames)(member=%s))"
+      start_tls = 0
-      role_scope: one
+      <start_tls_options>
-      role_field: cn
+        verify = none
-      role_value: dn
+      </start_tls_options>
-      role_search_options:
+      user_basedn = "ou=users,dc=example"
-        deref: always
+      user_filter = "(&(objectClass=inetOrgPerson)(cn=%s))"
+      user_scope = one
+      user_field = cn

+      # Important for role mappings to work:

+      role_value = dn
+      <role_search_options>

+      </role_search_options>
+  </config>
+  <role_mapping>
+    # Make all users in the hydra_admin group Hydra admins
+    hydra_admin = admin
+    # Allow all users in the dev group to restart jobs and cancel builds
+    dev = restart-jobs
+    dev = cancel-builds
+  </role_mapping>
+</ldap>
+```
+
+Then, place the password to your LDAP server in `/var/lib/hydra/ldap-password.conf`:
+
+```
+bindpw = the-ldap-password
+```
+
+### Debugging LDAP
+
+Set the `debug` parameter under `ldap.config.ldap_server_options.debug`:
+
+```
+<ldap>
+  <config>
+    <store>
+      <ldap_server_options>
+        debug = 2
+      </ldap_server_options>
+    </store>
+  </config>
+</ldap>
+```
+
+### Legacy LDAP Configuration
+
+Hydra used to load the LDAP configuration from a YAML file in the
+`HYDRA_LDAP_CONFIG` environment variable. This behavior is deperecated
+and will be removed.
+
+When Hydra uses the deprecated YAML file, Hydra applies the following
+default role mapping:
+
+```
+<ldap>
+  <role_mapping>
+    hydra_admin = admin
+    hydra_bump-to-front = bump-to-front
+    hydra_cancel-build = cancel-build
+    hydra_create-projects = create-projects
+    hydra_restart-jobs = restart-jobs
+  </role_mapping>
+</ldap>
+```
+
+Note that configuring both the LDAP parameters in the hydra.conf and via
+the environment variable is a fatal error.
