#### Server Side Sorting <a id="ldap-server-side-sort"></a>
Icinga Web automatically detects whether the LDAP server supports server side sorting.
If that is not the case, results get sorted on the client side.
There are LDAP servers though which report that they support this feature in general but have it disabled for certain
fields. This may lead to failures. With `disable_server_side_sort` it is possible to disable server side sorting and it
has precedence over the automatic detection.
