Grouping similar users to profiles

I added 3 groups called tier1,2 and 3 like
cn=tier3,ou=People,dc=somedomain,dc=com and added a user to that group.
That user is not able to log on.  Here is the output.  Note the "member="
and "uniquemember=".  Ldap-UserDn values are null???

 [ldap] performing search in ou=People,dc=somedomain,dc=com, with filter
(&(cn=tier3)(|(&(objectClass=GroupOfNames)(member=))(&(objectClass=GroupOfUniqueNames)(uniquemember=))))

  [ldap] object not found
