I read rfc3325 and I think I got it.
But the requirements here are to  provide alias support even for entities
that doesn't support PPI/PAI (or RPID).
So we were looking for a way to do it using the dbaliases table, based on
the identity in the header From.

But for the cases where the client/gw does support PPI/PAI, let me see if I
got it correctly:

Currently, we perform authentication using module auth_db.
To use PPI we should move to auth_radius and use

if (!radius_proxy_authorize("$pd", "$pU")) { # Realm and URI user are taken
	proxy_challenge("$pd", "1");         # from P-Preferred-Identity
};                                           # header field

If all goes well, we can use append_hf to send the PPI as PAI or
append_rpid_hf (rpid was fetched into avp during authentication), depending
on gw capabilities. Is this correct?
