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 9 Sumit Bose 2017-06-02 13:00:09 UTC 
Do you see any related messages in krb5kdc.log on the IPA server? Did you try to restart kdb5kdc on the IPA server to force to reload the UPN suffixes?
Comment 10 Sudhir Menon 2017-06-02 18:35:32 UTC 
Tested on RHEL7.3.z using


ipa-server-4.4.0-14.el7_3.7.x86_64
sssd-1.14.0-43.el7_3.18.x86_64
samba-4.4.4-13.el7_3.x86_64
selinux-policy-3.13.1-102.el7_3.16.noarch
krb5-server-1.14.1-27.el7_3.x86_64
389-ds-base-1.3.5.10-21.el7_3.x86_64
pki-server-10.3.3-18.el7_3.noarch


After restarting krb5kdc service, i am able to login using trusted user having UPN set.
