I managed it to define and assign the wanted LDAP attributes in the reply messages by defining them in the LDAP module. I am quite finished now but have one question left: All types of my VLAN settings are kept in profiles. In the settings of a device is a "radiusProfileDN" attribute pointing to the profile like cn=PRINTER,ou=VLAN,ou=profiles,ou=radius,dc=compend,dc=com where i.e. radiusTunnelPrivateGroupID and others are defined. Right now, the server is not going to resolve the radiusProfileDN. Do I have to define here also a matching pair of radius and LDAP attribute which is in module ldap group section treated with filter definitions? I put the 4 lines of ldap module of group handling, because the server is not diving in. this section at all. filter = '(objectClass=radiusprofile)' name_attribute = cn membership_attribute = 'radiusProfileDN' membership_filter = "(|(member=%{control:Ldap-UserDn})(memberUid=%{%{Stripped-User-Name}:-%{User-Name}}))" Thanks in advance. juergen
