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 Glen Babiano 2019-11-18 05:04:17 UTC 
Description of problem:
This is a AD direct integration setup as follows:

1. RHEL hosts are joined to inf.nz.example.com
2. AD users are located in corp.nz.example.com
3. Transitive trust established under nz.example.com
4. Forest root is au.domain.com

Version-Release number of selected component (if applicable):
RHEL 7.7

How reproducible:
Specific to customer environment.

Actual results:
RHEL hosts in inf.nz.example.com are not able to resolve AD users from corp.nz.example.com

Expected results:
RHEL hosts in inf.nz.example.com should be able to resolve AD users from corp.nz.example.com since there is a transitive trust established between these domains.
