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.

Fixed In Version: ipa-2.1.0-1.el6
Doc Type: Bug Fix
Doc Text:
Cause: The default sssd configuration does not store passwords if offline. Consequence: If the machine is disconnected from the network sssd will be unable to authenticate users. Fix: Set krb5_store_password_if_offline to True in sssd.conf by default. There is an ipa-client-install option --no-krb5-offline-passwords if this is not desired. Result: Passwords are stored by default.

Red Hat Product Errata RHSA-2011:1533 0 normal SHIPPED_LIVE Moderate: ipa security and bug fix update 2011-12-06 01:23:31 UTC

Description Marko Myllynen 2011-06-20 08:36:07 UTC 
Description of problem:
A common use case is when a user logs in while offline, then goes online (e.g., after establishing a VPN connection) and then tries to access IPA hosts/services. This fails currently because no Kerberos ticket is available after an offline login. It would be nice if ipa-client-install would configure (at least optionally) SSSD to store password if offline (i.e., set krb5_store_password_if_offline in sssd.conf for the domain).

Comment 6 Namita Soman 2011-10-14 19:30:15 UTC 
Installed client using command:
 ipa-client-install --domain=testrelm --realm=TESTRELM -p admin -w <xxx>

sssd.conf has krb5_store_password_if_offline = True

Verified request above using steps below::
1. Logged in as user test
2. kdestroy - no cached cred.
3. Client's network is stopped
4. log out user test
5. log back user test
6. And user test can log in offline
7. klist shows:
Ticket cache: FILE:/tmp/krb5cc_618800003_nNXtCe
Default principal: one@TESTRELM

Valid starting     Expires            Service principal
12/31/69 19:00:00  12/31/69 19:00:00  krbtgt/TESTRELM@TESTRELM
8. Restarted network service
9. After a few minutes, klist shows:
Ticket cache: FILE:/tmp/krb5cc_618800003_nNXtCe
Default principal: one@TESTRELM

Valid starting     Expires            Service principal
10/14/11 15:11:10  10/15/11 15:11:10  krbtgt/TESTRELM@TESTRELM
10. Can ssh as this user to master, without being prompted to reenter password.

Verified using ipa-client-2.1.2-2.el6.x86_64
