I don't actually want to add radiusprofile attributes to my LDAP.  The
users already have an attribute which identifies their department.  I
want to be able to say if "department attribute = X then allocate VLAN
Y".  Can this be done without specifically setting the vlan etc as
radiusprofile attributes.  Also I am not using ldap for the
authentication, just authorization.  The authentication is done using
ntlm_auth.
