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-1.16.2-13.el7_6.1
Doc Type: Bug Fix
Doc Text:
Previously, if a user had a non-standard home directory and did not have explicit mapping to an SELinux user, the SSSD service skipped setting this user's login context due to a bad optimization in the code. This update removes the optimization. As a result, SSSD now sets the SELinux login context even for users with a non-standard home directory and no explicit mapping to an SELinux user.

Hi Michal, this needs packaging.
Comment 10 Jakub Hrozek 2019-01-17 12:05:38 UTC 
Can you show me some logs? (selinux_child and domain) ?

btw you don't have to add a selinux user or a role. Just with the default configuration, logging in as the user should add that user to the database
