Description John Dennis 2013-03-28 12:37:13 UTC

realmd might already know about the domain (i.e. from reading the sssd config), but if you call Discover on that domain it will fail unless there are DNS SRV records for the domain. realmd should be able to discover a domain it already knows about instead of failing.

$ hostname

realm: No such realm found: xxx.com

Fallback to configured realms when discovering

 * If no discovered realms for a string, check locally configured
   realms to see if they're available locally, but just not
   online right now.
 * Reorganize how realms are enumerated on a provider, so that
   we can accomplish the above generically

This is ready for review.
