Kerberos Caches
How to clear Kerberos Credentials Caches
AD Bridge (ADB) does not support clearing Kerberos cache files (typically stored in /tmp as krb5cc_xxxxx). However, since these files reside in /tmp, they are automatically removed upon system restart. Additionally, they can be manually deleted without impacting the functionality of ADB, provided that Kerberos and AD Bridge are functioning correctly.
The cache will regenerate automatically when needed.
/opt/pbis/bin/kdestroy
Adding the following to /etc/bash.bash_logout will remove the current user's cache file at logoff.
The below command to delete the current user's cache file, or with -c username to delete another user's (with root permission):
/opt/pbis/bin/kdestroy
Refer to Kerberos commands in ADB for more information.
