LDAP integration not working as I want it

Hej there,

I am trying to integrate LDAP authentication for a nextcloud server. Unfortunately the group selection in users tab has been greyed out with comment, that my LDAP server doesn’t support “member of” feature. This is true, but the “member of overlay” in openLDAP has been deprecated.

Right now the behaviour is: any user listed in my LDAP is able to log on against my Nextcloud. But just 2 of 3 users are in my “Nextcloud” group in LDAP. What I want is, that only the users in “Nextcloud” group (in LDAP) can login. All other users shouldn’t be able to do so.

Any ideas how I can get this working properly

Kind regards
