How to reproduce the issue

When querying a non-cached group membership by name, debug output states that the object the user is a member of was the parent of the group object.

if (&LDAP-Group == 'my-group') {
   # success
}

Will emit a debug message similar to ou=groups,dc=example,dc=com when it should be cn=my-group,ou=groups,dc=example,dc=com.
