Add the User-Profile attribute. This is used by the rlm_ldap module and contains
the DN for an entry containing check and reply radius attributes. If it is set
it will be used instead of the default_profile directive. The idea is to use different
user profiles based on checks done in the users file. That way we can do something like
this:

DEFAULT	Service-Type == Outbound-User, User-Profile := "uid=outound-dialup,dc=company,dc=com"

The same idea could also work for the sql module, to select groups containing radius attributes
without having the user belong to them based only on checks on the incoming Access-Request
