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.

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/1746

If use_fully_qualified_names is true, sss tools(like sss_useradd) should proceed only if fqdn was given or print an error message if not.

To reproduce:

configure use_fully_qualified_names=true in sssd.conf, restart sssd.

Run the tools with a raw, non-fqdn username, such as "sss_useradd someuser".

Expected results:
should not work, the name is not fully qualified

Actual results:
Works

Fixed upstream.

Temporarily moving bugs to MODIFIED to work around errata tool bug

Verified the bug on SSSD Version: sssd-1.11.2-10.el7.x86_64

Steps followed during verification:
1. Setup sssd.conf domain with use_fully_qualified_names = true
2. Add a user without fqdn, using sss_useradd command --

[root@rhel-7 sssd]# sss_userdel someuser
Name 'someuser' does not seem to be FQDN ('use_fully_qualified_names = TRUE' is set)
Invalid domain specified in FQDN

3. As expected, an error message is displayed. User gets added only when fqdn is used with user name say, someuser@LOCAL.

[root@rhel-7 sssd]# sss_useradd someuser@LOCAL
[root@rhel-7 sssd]# 
[root@rhel-7 sssd]# getent passwd -s sss someuser@LOCAL
someuser@LOCAL:*:1000:1000:someuser:/home/someuser:/bin/bash
