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 Radek Steiger 2015-03-16 16:34:08 UTC
> Description of problem:

When a non-existent ACL role is referenced within creating a user/group, pcs errors out with invalid CIB. 

[root@virt-041 ~]# pcs acl user create MyUser TestRole
Error: Unable to update cib
Call cib_replace failed (-203): Update does not conform to the configured schema
<cib crm_feature_set="3.0.9" validate-with="pacemaker-2.3" epoch="344" num_updates="0" admin_epoch="0" cib-last-written="Mon Mar 16 17:25:35 2015" have-quorum="1" dc-uuid="2">
...

[root@virt-041 ~]# pcs acl group create MyGroup TestRole
Error: Unable to update cib
Call cib_replace failed (-203): Update does not conform to the configured schema
<cib crm_feature_set="3.0.9" validate-with="pacemaker-2.3" epoch="345" num_updates="0" admin_epoch="0" cib-last-written="Mon Mar 16 17:32:51 2015" have-quorum="1" dc-uuid="2">
...

The relevant ACL part, where role definition is missing:

...
<acls>
  <acl_target id="MyUser">
    <role id="TestRole"/>
  </acl_target>
</acls>
...

We should check if the role exists before adding a user.
