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.

Comment 5 amitkuma 2019-08-22 12:22:36 UTC 
Thanks sumit.
Will convey the information to customer.
Comment 6 Sumit Bose 2019-08-22 18:58:50 UTC 
Although the customer issue is solved this ticket should be used to track some improvements to the sss-certmap man page and to
https://docs.pagure.org/SSSD.sssd/design_pages/certmaps_for_LDAP_AD_file.html especially about regular expressions and about escaping special characters.

I would suggest to rename the bug, then and provide a summary. Otherwise we risk someone going 'oh, I bet my customer is hitting THIS' and linking a case here without reviewing the whole bugzilla.
Comment 8 amitkuma 2019-08-23 07:21:34 UTC 
Worked:
[certmap/localDomain/user]
matchrule = <SUBJECT>CN=.*\(user\).*<EKU>msScLogin

Does not work:
[certmap/localDomain/user]
matchrule = <SUBJECT>CN=.*(user).*<EKU>msScLogin

1. Should have text the describe the situation.
- https://docs.pagure.org/SSSD.sssd/design_pages/certmaps_for_LDAP_AD_file.html 
- # man sss-certmap 
2. If possible sssd should provide warning in logs clarifying escape character need to be added.

Verified:

Version ::

sssd-2.2.3-6.el8.x86_64
libsss_certmap-2.2.3-6.el8.x86_64

Results ::

[root@rhel8-5 sssd]# man sss-certmap|egrep "Admin|Please note that the characters"
           Please note that the characters "^.[$()|*+?{\" have a special meaning in regular expressions and must be escaped with the help of the '\'
           Example: <SUBJECT>^CN=.* \(Admin\),DC=MY,DC=DOMAIN$
