Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Please attach AVCs that you see when reproducing this scenario.
Comment 3 Roshni 2016-02-05 15:18:26 UTC 
I have not yet reproduced this issue on RHEL 7 but once https://bugzilla.redhat.com/show_bug.cgi?id=1303214 is fixed we will be running into this issue. The same happened on RHEL 6.8, the AVC's on RHEl 6.8 can be found here https://bugzilla.redhat.com/show_bug.cgi?id=1299066#c7
Comment 4 Milos Malik 2016-02-05 16:00:00 UTC 
Some of the AVCs listed in BZ#1299066 contain "success=no", which means they appeared in enforcing mode. The selinux-policy developers need to see all AVCs triggered by the scenario to fix it properly in policy. Could you switch the sssd_t type to permissive and repeat your scenario?

# setenforce 1
# semanage permissive -a sssd_t
(repeat your scenario)
# semanage permissive -d sssd_t
Comment 5 Roshni 2016-02-08 22:39:42 UTC

Comment 6 Lukas Vrabec 2016-05-04 14:49:37 UTC 
Roshini, 

This is rhel7 bug and AVC si fixed in:
[root@hp-dl380pgen8-02-vm-5 ~]# rpm -q selinux-policy 
selinux-policy-3.13.1-60.el7_2.3.noarch

Can we close this for RHEL7?
