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:
Cloned from https://pagure.io/SSSD/sssd/issue/3420
Setup
An IPA enrolled client, configured with kcdproxy in /etc/krb5.conf and having the following entries in /etc/sssd/sssd.conf:
cache_credentials = True
krb5_store_password_if_offline = True
As long as the host is online when logging in, everything works as expected. And the logged in user have a valid kerberos ticket instantly.
But if the host is offline (wlan disabled, no ethernet), the cached credentials are not considered for the authentication and the authentication fails. The gdm interface says "Authentication failed".
Workaround
Disable the kdcproxy in /etc/krb5.conf, and logging in works when being offline. Drawback is that there will be no kerberos ticket available until the host is connected to a network or VPN which enables access to the IPA/KDC server.
Version-Release number of selected component (if applicable):
How reproducible:
Always
Steps to Reproduce:
1. Change /etc/krb5.conf to use proxy
2. Go Offine
3. Try to authenticate
4. Fail to authenticate
Actual results:
Expected results:
Offline Authentication should also work if the KdcProxy functionality is used.
