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.

Description Kaushik Banerjee 2012-11-27 09:56:44 UTC

Description of problem:
krb5_kpasswd failover doesn't work

Version-Release number of selected component (if applicable):
sssd-1.9.2-25.el6

How reproducible:
Always

Steps to Reproduce:
1. domain section of sssd.conf includes:
auth_provider = krb5
krb5_server = kdc.example.com:12345,kdc.example.com:88
krb5_kpasswd = kdc.example.com:12345,kdc.example.com:464

2. Try to login and change the user's password
# ssh -l puser1 localhost
puser1@localhost's password:
Last login: Tue Nov 27 14:46:43 2012 from localhost
-sh-4.1$ passwd
Changing password for user puser1.
Current Password:
New password:
Retype new password:
passwd: Authentication token manipulation error
-sh-4.1$

  
Actual results:
Password change fails as sssd is unable to failover.

/var/log/secure shows:
Nov 27 14:51:56 dhcp201-200 passwd: pam_sss(passwd:chauthtok): system info: [Cannot contact any KDC for requested realm]
