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 Alexey Tikhonov 2020-05-11 09:06:34 UTC 
This bug was initially created as a copy of Bug #1829806

I am copying this bug because: to track fix for RHEL8



Description of problem:
sssd keeps logging the following message at debug level 'SSSDBG_MINOR_FAILURE':
    (Mon Apr 20 15:11:02 2020) [sssd[nss]] [calc_flat_name] (0x0080): Flat name requested but domain has noflat name set, falling back to domain name


Version-Release number of selected component (if applicable): n/a


How reproducible:
In most cases with sssd connected to AD.


Steps to Reproduce: n/a

Actual results:
Message is logged way too often.


Expected results:
Message is (eventually) logged once, at eg. startup and not on a regular basis.


Additional info:
* Linked upstream issue
* Linked upstream PR - not yet merged, but Sumit has basically agreed on it already
* Linked customer case

I'd be happy if we could get this fixed in RHEL7/8 + all active EUS/E4S z-streams as soon as the PR is has been merged. Please clone as necessary for these different releases.

1. Start sssd service following messages is noticied
 
2. Lookup users

foo1@example1:*:14583101:14564100:foo1 User::/bin/bash

Verify if the message "Flat name requested but domain has noflat name set, falling back to domain name" is seen in logs.
