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 2013-01-13 15:23:47 UTC

Description of problem:
Failover to ldap_chpass_backup_uri doesn't work

Version-Release number of selected component (if applicable):
1.9.2-68

How reproducible:
Always

Steps to Reproduce:
1. Domain section in sssd.conf:
ldap_search_base = dc=example,dc=com
id_provider = ldap
ldap_uri = ldap://ldapsrv.example.com
ldap_chpass_uri = ldap://invalidsrv.example.com
ldap_chpass_backup_uri = ldap://ldapsrv.example.com

2. Try to change the password of a user:

# ssh -l puser1 localhost
puser1@localhost's password: 
Last login: Fri Jan 11 20:49:34 2013 from localhost
-sh-4.1$ passwd
Changing password for user puser1.
Current Password: 
System is offline, password change not possible
passwd: Authentication token manipulation error
-sh-4.1$ 

  
Actual results:
Password change fails. Looks like failover to ldap_chpass_backup_uri doesn't happen. 

Logs show:
