The Kerberos v4 Properties dialog is accessible from the Options
menu.
Here, you can specify the name of the in-memory cache used to store
the Kerberos 4 tickets. The format of the name is “API:” followed
by the cache name. Disk caches are not supported by Kerberos for
Windows.
The paths to the Kerberos 4 configuration files: krb.con and
krbrealm.con may be changed from this dialog if necessary. The
default is to store the configuration files in the Windows directory.
