+Active Directory
+~~~~~~~~~~~~~~~~
+
+Proxmox Backup Server can also utilize external Microsoft Active Directory
+servers for user authentication.
+To achieve this, a realm of the type ``ad`` has to be configured.
+
+For an Active Directory realm, the authentication domain name and the server
+address must be specified. Most options from :ref:`_user_realms_ldap` apply to
+Active Directory as well, most importantly the bind credentials ``bind-dn``
+and ``password``. This is typically required by default for Microsoft Active
+Directory. The ``bind-dn`` can be specified either in AD-specific
+``user at company.net`` syntax or the commen LDAP-DN syntax.
+
+The authentication domain name must only be specified if anonymous bind is
+requested. If bind credentials are given, the domain name is automatically
+inferred from the bind users' base domain, as reported by the Active Directory
+server.
+
+A full list of all configuration parameters can be found at :ref:`domains.cfg`.
+
+.. note:: In order to allow a particular user to authenticate using the Active
+  Directory server, you must also add them as a user of that realm in Proxmox
+  Backup Server. This can be carried out automatically with syncing.

 User synchronization can started in the GUI at
 Configuration > Access Control > Realms by selecting a realm and pressing the
 `Sync` button. In the sync dialog, some of the default options set in the realm
 configuration can be overridden. Alternatively, user synchronization can also
-be started via the ``proxmox-backup-manager ldap sync`` command.
