Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Description Martin Kosek 2014-02-27 18:31:18 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/4202

If trust was created and then we attempt to re-establish it with AD admin credentials that don't have enough privileges, we'll fail -- either at the attempt to delete previously created trust or at the attempt to create new trust.

When we delete existing trust, we silence any exception and don't see NT_STATUS_ACCESS_DENIED, so there will be name collision when we would next create the trust with the same name:
{{{
# echo Test1234 | ipa trust-add ad.test --admin abbra --passwordipa: ERROR: CIFS server communication error: code "-1073741771",
                  message "NT_STATUS_OBJECT_NAME_COLLISION" (both may be "None")
}}}

Actual cause for this collision is access denial at the trust delete stage, so we need to report proper error message by catching proper exception.
