5.10. Enabling the tracking of last successful Kerberos authentication for users in IdM
For performance reasons, Identity Management (IdM) running in Red Hat Enterprise Linux 8 does not store the time stamp of the last successful Kerberos authentication of a user. As a consequence, certain commands, such as ipa user-status, do not display the time stamp.
Prerequisites
- You have obtained the ticket-granting ticket (TGT) of an administrative user in IdM.
-
You have
rootaccess to the IdM server on which you are executing the procedure.
Procedure
Display the currently enabled password plug-in features:
# ipa config-show | grep "Password plugin features" Password plugin features: pass:quotes[AllowNThash], pass:quotes[KDC:Disable Last Success]The output shows that the
KDC:Disable Last Successplug-in is enabled. The plug-in hides the last successful Kerberos authentication attempt from being visible in the ipa user-status output.Add the
--ipaconfigstring=featureparameter for every feature to theipa config-modcommand that is currently enabled, except forKDC:Disable Last Success:# ipa config-mod --ipaconfigstring='AllowNThash'This command enables only the
AllowNThashplug-in. To enable multiple features, specify the--ipaconfigstring=featureparameter separately for each feature.Restart IdM:
# ipactl restart
