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:
This is a spin-off of https://bugzilla.redhat.com/show_bug.cgi?id=1383520 which, instead changing the default re_expression (which might be too risky in a stable RHEL version) would document how to change the expression for environments that use groupnames with an @-sign.

Additional info:
version:
ipa-server-4.6.4-7.el7.x86_64
ipa-server-trust-ad-4.6.4-7.el7.x86_64
sssd-1.16.2-12.el7.x86_64
sssd-ad-1.16.2-12.el7.x86_64
Steps:
1. Install IPA master and setup AD trust
2. Add a user on AD side having @ i.e test@riz
3. Add a group on AD having @ i.e test@test
4. Add user to the the added group in step 3
5. clear cache and restart sssd on ipa server
6. Run id and getent for user and group on ipa server
$ id test@riz@ad-domain
$ getent group test@test@ad-domain
7. Install Ipa client
8. set regex on sssd.conf on ipa client in section [domain] and [sssd] and restart the sssd:
[..]
re_expression = ((?P<name>.+)@(?P<domain>[^@]+$))
use_fully_qualified_names = True
debug_level = 9
[sssd]
services = nss, sudo, pam, ssh
re_expression = ((?P<name>.+)@(?P<domain>[^@]+$))
debug_level = 9
[..]
9. 6. Run id and getent for user and group on ipa client
$ id test@riz@ad-domain
$ getent group test@test@ad-domain
Actual result:

Currently '@' sign works for user name only and not for group names. Hence marking the bug as verified.
