We have set a Once way trust from AD to KDC and validated that we were able to get tickets from AD.
Kerberos Realm - ABC.NET
AD Domain - XZY.COM
Validation
kinit ad_user@XYZ.COM
List Showed the valid ticket.
Now in just few hrs the trust is broken the same command, kinit ad_user@XYZ.COM, gives
kinit: Cannot find KDC for realm "XYZ.COM" while getting initial credentials.
Thanks in advance. Just want to hit myself on the face.
