[Serusers] users authentication

[Joao Pereira]

Hello
I already have a SER runnig nicelly.
Now I installed a second SER (with other domain) with the same database 
configuration and the same ser.cfg (except the IP).
Everyting works fine... except the authentication... SER always answers 
401 Unauthorized.

It only accepts clients when I comment this part:

    if (!www_authorize("newdomain.com", "subscriber")) {
         www_challenge("newdomain.com", "0");
         break;
      };


The users exist in the database and I know the username / password.
Whats happening?
Thanks
regards
Joao Pereira
