This configuration parameter specifies how frequently in minutes to check the Kerberos cache for credentials that belong to users who are not logged on. If the user is not logged on, the credentials are deleted.

The parameter value should be a positive integer. Setting this parameter to zero disables periodic clean-up of the cache.

For example, to set the clean-up interval to 5 minutes:

krb5.cache.clean.interval: 5

The default value for this parameter deletes the credential cache for users who have logged off every one minute.
