ldap filter not working

[MarvinKlar]

Hello everyone,

I currently try to configure Discourse to only allow users in a specific ldap group to log in.

My plugin configuration: ldap enabled: true ldap hostname: the hostname of my ldap server ldap port: 389 ldap method: plain ldap base: the base of my ldap server ldap uid: userPrincipalName ldap bind dn: Nothing ldap password: Nothing ldap filter: (&(userPrincipalName=%{username})(memberOf=cn=[the name of the required group],ou=....,[base]))

When using this configuration, nobody can log in to the forum. When I use the bind dn and password, everybody can log in. I also tried this filter without success (copied from my ldap servers filter): (&(&(&(userPrincipalName=%{username})(memberOf=[dn of the group]))))

What do I have to configure, to only allow users in that specific group to log in?

I didn't found any errors or indicators in the log. Please help!

Thanks fou your help and attention!
