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.

Fixed In Version: sssd-1.12.2-32.el7
Doc Type: Bug Fix
Doc Text:
The following known issue description has been removed from the RHEL 7.1 Beta Release Notes: The Kerberos provider of SSSD does not take into account that UIDs can be overridden with the views functionality, which is new in Red Hat Enterprise Linux 7.1. In addition, if a user has his UID overridden, the original UID is used instead. Consequently, using an incorrect UID can, for example, cause failures when creating the Kerberos keyring cache. No workaround is available at the moment.

Description Jakub Hrozek 2014-11-27 17:09:30 UTC 
Description of problem:
The Kerberos provider does not handle views properly. This can result in strange behaviour, like the ccache being created with the original UID instead of the overriden one.

Version-Release number of selected component (if applicable):
sssd-1.12.2-28.el7

How reproducible:
always

Steps to Reproduce:
1. Assign an UID override on the server side
2. Log in to the client. Run "id" to make sure the ID is as expected
3. run klist

Actual results:
An error message, complaining that ccache is not present in the keyring for the specified UID

Expected results:
The ccache should be printed correctly.
