Restrict login for users from specific group - LDAP


I have to say in advance, that my Nextcloud environment is currently running on version 15.0.7 which is no longer supported.

I’m trying to restrict user access to Nextcloud using LDAP querys for groups.

If I set the LDAP query and click on “Verify settings and count the groups”, the group that should have access is found. But it is not clear to me how I can activate the filter so that only users belonging to this group can log into the Nextcloud environment.

Thanks for your help.
