LDAP login attributes not updating.

[Jookadin]

Steps to reproduce

1. Add new group under Users and Groups in LDAP configuration.

Expected behaviour

The login attributes filter should update with the new group that was just added.

Actual behaviour

The login attributes filter stays the same, resulting in the new groups users being added, but are not able to login.

Workaround

It was possible to get the login attributes to update by removing the LDAP/AD-username checkmark, and adding it again.
