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.

Expected results:
No denials

Additional info:
This error is related only to slapd resource in cluster. Attempt to start slapd service without cluster doesn't cause denial error. After fix is available, we can perform its testing in cluster.
Comment 2 Lukas Vrabec 2017-10-12 12:17:57 UTC 
We're going to close this bug as WONTFIX because

 * of limited capacity of selinux-policy developers
 * the bug is related to EPEL component or 3rd party SW only
 * the bug appears in unsupported configuration 

We believe this bug can be fixed via a local policy module.

hm...

what EPEL component are you refering to?

>  * the bug appears in unsupported configuration 

how is that configuration unsupported?

> If you disagree, please re-open the bug.

I disagree, hence reopening the bug.

The configuration is standard clustered configuration of slapd daemon. Cluster components (pcs, pacemaker and others) are part of High Availability addon (hence part of RHEL). Configuration is done via standard resource agents so perfectly valid as far as I can tell.

We do support selinux on all cluster resources to my knowledge. If that has changed in any way, please point me to relevant discussion where this has been decided.

Thank you,

Please disregard comment#2 and comment#3.

Wrong keyword was used in the Devel whiteboard -> mass BZ switch got a wrong list of BZs.
