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 Striker Leggette 2017-06-16 19:47:33 UTC 
[+] Description of problem:
 - Active Directory GPOs which are applied to Linux hosts per their security filtering should be properly handled by SSSD.  At the moment, GPOs can only be applied to Linux hosts which live within the OU that the GPO is linked to.

Comment 9 Michal Zidek 2018-11-12 12:10:27 UTC 
I am just adding a short summary for convenience:

On Win server machine it is possible to specify security filter for each GPO. This filter can contain users, groups and host entries. The meaning of the filter is "this GPO is applicable only if we deal with entries specified in this list".

SSSD currently ignores the host entries and only works with user and group entries so if the list contains host A and no users/groups SSSD will always evaluate the GPO as not applicable even if users log into host A.
Comment 13 Michal Zidek 2020-07-29 07:58:36 UTC 
Sorry I have not answered the question before. I do not remember what the behaviour should be exactly, but as a rule of thumb we always wanted to have the behaviour as close to Windows clients as possible, so whatever Windows clients are doing in that situation SSSD should do the same.
