Fixed In Version: krb5-1.10.3-20.el6
Doc Type: Bug Fix
Doc Text:
Cause: The init script which launches the KDC runs a diagnostic helper first, attempting to diagnose a common upgrade-related error. When there is no default realm configured in /etc/krb5.conf, even if a realm name is set in /etc/sysconfig/krb5kdc, the helper would fail. Consequence: The attempt to start the KDC would fail. Fix: A realm set in the /etc/sysconfig/krb5kdc configuration file is also explicitly passed to the helper on its command line. Result: This error no longer occurs.

Description Nikolai Kondrashov 2013-09-18 06:43:26 EDT 
Description of problem:
When default realm is set only in /etc/sysconfig/krb5kdc, but neither in DNS nor in /etc/krb5.conf, /etc/init.d/krb5kdc produces the following error message:

    Error getting default realm: Configuration file does not specify default realm.

This message is being output by kdb_check_weak, which is not supplied the configured realm (contrary to krb5kdc itself).

Version-Release number of selected component (if applicable):
krb5-server-1.10.3-10.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Specify default realm in /etc/sysconfig/krb5kdc
2. Make sure default realm is specified neither in DNS nor in /etc/krb5.conf
3. Execute "service krb5kdc restart"

Actual results:
Stopping Kerberos 5 KDC:                                   [  OK  ]
Error getting default realm: Configuration file does not specify default realm.
Starting Kerberos 5 KDC:                                   [  OK  ]

Expected results:
Stopping Kerberos 5 KDC:                                   [  OK  ]
Starting Kerberos 5 KDC:                                   [  OK  ]
