Kerberos v4 Properties… Command, Ctrl+4

The Kerberos v4 Properties dialog is accessible from the Options menu.

Kerberos Four Properties

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.
