Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
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 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 ]
