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 of problem:
In case of trusted domains, realmd fails to validate all the trusted domains.

Version-Release number of selected component (if applicable):
realmd-0.14.5-1.el7

How reproducible:
Always

Steps to Reproduce:
1. Join to an AD domain sssdad.com via realmd
2. Now try to permit an user from another trusted domain sssdad1.com

# realm permit abcd
See: journalctl REALMD_OPERATION=r2005410.20779
realm: Couldn't change permitted logins: Invalid login argument 'abcd' does not match the login format.


Actual results:
realmd fails to permit the user from the trusted domain

Expected results:
realmd should relax domain validation, and should permit users from other domains.

Additional info:

The trusted domains are discovered on the fly, so currently I don't see a way of validating them. Maybe there could be a switch for realm permit that would override the check?

Does sssd allow use of trusted domains in the simple allow/deny config lines? If so, in which version of sssd was this added? I remember us discussing it, but must have missed the resolution.

In my opinion, this point we should bump this to RHEL 7.1 (or later). This is (or was until recently) a fundamental limitation of sssd.

Not at the moment, the simple provider didn't even support FQDNs at all until recently.

We'll be adding subdomain support in time for 7.0. But I agree this realmd RFE is not critical for 7.0.
