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.
*winbindd* crashes when installing a new AD trust
When configuring a new Active Directory (AD) trust on a newly installed system, the *ipa-adtrust-install* utility might report that the *winbindd* service terminated unexpectedly. Otherwise, *ipa-adtrust-install* completes successfully.
If this problem occurs, restart the IdM services by using the "ipactl restart" command after running *ipa-adtrust-install*. This also restarts *winbindd*.
Note that the full extent of the functional impact of this problem is still unknown. Some trust functionality might not work until *winbindd* is restarted.
This Bug was triaged and discussed during IPA sync meeting and is considered as interim failure that was triggered on unclean machine. Varun Mylaraiah (CCed) tested current IdM installation with Trusts and it was working OK.
We agreed that this bug can be now closed.
Description of problem: crash report is generated in /var/spool/abrt when ipa-adtrust-install is run Version-Release number of selected component (if applicable): Red Hat Enterprise Linux Server release 6.9 Beta (Santiago) ipa-server-3.0.0-51.el6.x86_64 ipa-server-selinux-3.0.0-51.el6.x86_64 ipa-server-trust-ad-3.0.0-51.el6.x86_64 How reproducible: Always Steps to Reproduce: 1. Install IPA server 2. ipa-adtrust-install Actual results: ipa-adtrust-install command runs without any error, but there is crash report generated.
