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
vm-054.xxx.com
$ realm list
xxx.com
  type: kerberos
  realm-name: XXX.COM
  domain-name: xxx.com
  configured: kerberos-member
  server-software: freeipa
  client-software: sssd
  required-package: freeipa-client
  required-package: sssd-tools
  required-package: sssd
  login-formats: %U@xxx.com
  login-policy: 
$ realm discover -v xxx.com
 * Searching for kerberos SRV records for domain: _kerberos._udp.xxx.com
 * Searching for MSDCS SRV records on domain: _kerberos._tcp.dc._msdcs.xxx.com
 * Couldn't find kerberos DNS records for: xxx.com
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
Comment 2 Stef Walter 2013-04-25 11:03:40 UTC 
This is ready for review.
