Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

I had them change the ldap_schema to "ad" from "rfc2307bis" and they enabled enumeration, this appears to have stopped the segfaults.

Comment 4 Lukas Slebodnik 2014-09-09 15:43:51 UTC
The reason of crash is dereference of NULL pointer. I looked into log files, but they will not help us to reproduce problem. Can you reproduce bug locally?

Comment 9 Jakub Hrozek 2015-02-19 15:28:28 UTC
This bugzilla has no reproducer, testing should be sanity-only to make sure group memberships still work correctly.

Do you have any feedback from customer?
Did it fix crash?

We do not have a reproducer so any response from customer will help to verify this BZ.

Hey Lukas,

The customer responded right after you did.  See the above comment.

Comment 22 Dan Lavu 2015-06-01 17:37:18 UTC
This has been verified against sssd-client-1.12.4-42.el6.x86_64. Sanity only, since we do not have a good reproducer.
