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the product is no longer active in Red Hat Bugzilla.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.
Description of problem:
When restarting SSSD it checks the 'ccacheFile' attribute for users in db to see if there are any credential caches that should be monitored for renewal. This check does not work with caches of 'KEYRING' type.
The result is that SSSD is no longer able to renew kerberos credentials after a restart. Log message:
[check_ccache_files] (0x0200): Failed to check ccache file [KEYRING:persistent:60483].
Verified in email conversation with mr. Sumit Bose:
"Since the code is quite old (and the related test we have internally as well) nobody can to the idea the check the code for newer ccache types. The code explicitly checks if there is a _file_ with the name from the ccacheFile. So, it
you switch to FILE: type ccache for testing, restarting should work as
well."
Version-Release number of selected component (if applicable):
sssd-2.0.0-43.el8_0.3.x86_64
How reproducible:
Always
Steps to Reproduce:
1. set 'default_ccache_name = KEYRING:persistent:%{uid}' in krb5.conf
2. Set "krb5_renew_interval = 15s" and "debug_level=9" in sssd.conf to make debugging easier
3. Log in with username/password, thereby letting SSSD acquire kerberos credentials.
4. Monitor sssd logs and check for messages of type 'renew_all_tgts', which should pop up every 15s.
5. Restart SSSD
Actual results:
sssd fails to monitor credential cache for renewal with message:
[check_ccache_files] (0x0200): Failed to check ccache file [KEYRING:persistent:60483].
Expected results:
SSSD should keep checking credential cache for renewal
