[OpenSIPS-Users] Multiple domains all the same destination

[Schneur Rosenberg]

I have multiple domain names going to the same server, right now if I
don't have the domain field in the subscriber table set to the domain
I'm using to register it wont authenticate, because is_from_local()
will be false, how can I change that, that as long as the domain
points to  my ip address it should authenticate, I currently have the
domain module loaded and multi_domain enabled, is it supposed to be
that way?
