Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

It appeared after the following command:

python -m unittest realmd_lmi.TestRealmdFunctions.test_query

and when openssl was upgraded to openssl-1.0.2k-1.el7 from openssl-1.0.1e-60.el7.

selinux-policy-3.13.1-162.el7
tog-pegasus-2.14.1-4.el7
openlmi-realmd-0.5.0-4.el7
openssl-1.0.2k-1.el7

How reproducible:
always

Steps to Reproduce:
Join a machine to AD or IPA thorugh openlmi

Comment 2 Milos Malik 2017-06-16 19:37:04 UTC
Could you run the TC in permissive mode so that all SELinux denials are revealed?

# ausearch -m avc -m user_avc -m selinux_err -m user_selinux_err -i -ts today

Comment 3 Patrik Kis 2017-06-19 08:59:32 UTC
In permissive mode there are no AVC denials at all.
