Openshift_adm_groups_sync does not sync users from ldap groups

Hi.
I would like to sync groups of users from ldap to openshift. I tried openshift_adm_groups_sync module which creates empty groups (without users). Does anyone use this modul, because I cant find the issue? I use the same group-sync.yaml file for years and it works fine. But with openshift_adm_groups_sync users from ldap groups are not synced. Only empty groups are created so the issue is not with the ldap access.

      bindPassword:
        name: ldap-bind-password # Ensure this secret exists in the same namespace

      attributes:
        id: "uid" # Unique identifier for users
        preferredUsername: "uid"

      groupUID: "cn" # Unique identifier for groups
      groupName: "cn"
      groupMembership:
        - "memberUid" # Replace with your LDAP's group membership attribute
