Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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 Anton Bobrov 2022-03-11 12:17:20 UTC 
Description of problem:

This is to track https://krbdev.mit.edu/rt/Ticket/Display.html?id=9037 upstream ticket and possible solutions to it in the context of sssd.

The customer is experiencing https://access.redhat.com/solutions/3380341 on a regular basis. This occurs after the machine account needs to be renewed (every 30 days), but not every time, which is likely due to race condition described in the ticket above.
Comment 3 Alexey Tikhonov 2022-03-11 12:22:31 UTC 
Hi,

wouldn't 'adcli' component (executed under the hood by SSSD for this operation) be more suitable?

Perhaps "not" if proposed work-around is "retry by SSSD".
