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).

Are you using the ldap or sssd backend?

Comment 32 grzegorz krol 2017-09-12 08:19:09 UTC

I'm using Dell Quest (vas4 module).

Comment 43 Michael Starling 2017-09-12 14:54:27 UTC

I see this issue with the LDAP backend. We do not use the SSSD backend because it doesn't respect the sudo option "!root_sudo". We also like to keep our standard bind user in sssd.conf different from the user that searches for SUDO rules in /etc/sudo-ldap.conf. We have also found that we are unable to restrict ACLs as tightly for the bind user in sssd.conf as we are in sudo-ldap.conf.
