Okay, perfect that was part of the answer I needed, Thanks!
I guess I now have two more questions:
1. Is there a way to "manually" specify a proxy or Realm in the authorize section?
2. Is there a way to modify the Realms file to find a realm find the realm domain.name in from within user.domain.name. Whenever I try I only get the Realm name not domain.name. (i.e. I want it to pick up from the first . character not the last )
Thanks
