How looks auth_username?  "alice", "alice at domainA.org" or
"sip:alice at domainA.org"?
How do you handle a multidomain environment? For example: how to fill
the above table with these two users?:
  sip:alice at domainA.org
  sip:bob at domainB.net

Also, Kamailio has an option to use domain or not (in various
modules), so domain is checked or not (this improves the DB access in
single-domain environments).

Could you show an example of usage of uid column? which value does it contain?

This is great.

email_address was removed from subscriber table long time ago :)
