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 of problem:
'exclude_groups' option provided in SSSD for session recording (tlog) doesn't work as expected
Version-Release number of selected component (if applicable):
rhel-system-roles-1.0.1-1.el8.noarch
tlog-9-2.el8.x86_64
sssd-2.4.0-9.el8.x86_64
How reproducible:
Always
Steps to Reproduce:
1. Configure session recording in RHEL 8.4 as per https://access.redhat.com/solutions/4068941
2. Confirm if sessions are correctly being logged by tlog as expected.
3. Configure /etc/sssd/conf.d/sssd-session-recording.conf file to exclude members of an AD group from being recorded by tlog.
---
[session_recording]
scope=all
exclude_groups=adgroup
---
4. Check again if sessions for the members of excluded AD group are recorded or not.
Actual results:
Session for members of excluded AD group are recorded by tlog.
Expected results:
Session recording for members of excluded AD group should be skipped by tlog.
Additional info:
exclude_groups support was added in sssd as part of BZ https://bugzilla.redhat.com/show_bug.cgi?id=1895472 with ERRATA https://bugzilla.redhat.com/show_bug.cgi?id=1895472
