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 Amith 2017-05-30 13:11:05 UTC
Description of problem:
The format for KRB5CCNAME is KCM:$NAME:$CACHE_ID, when KCM cache is used. However this variable shows just "KCM:".

Version-Release number of selected component (if applicable):
sssd-1.15.2-37.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Run user login and fetch the krb ticket. 
    # ssh -l testuser localhost
    [testuser@vm-idm-020 ~]$ klist
    Ticket cache: KCM:21201:48692
    Default principal: testuser

2. Verify the contents of variable KRB5CCNAME
   [testuser@vm-idm-020 ~]$ echo $KRB5CCNAME
   KCM:

Result Seen:
KCM:

Expected results:
The KRB5CCNAME variable should be in the form of KCM:$NAME:$CACHE_ID.
It should show relevant field values.

Comment 2 Jakub Hrozek 2017-05-30 13:22:19 UTC
No, this is by design. The collection is identified just by KCM.

I admit this got me confused as well, but see the reply from the upstream MIT Kerberos maintainer:
