> ktab (Linux) (Windows)
> ktab is a command-line tool that allows the user to manage the principal
> names and service keys stored in a local key table. Principal and key
pairs
> listed in the keytab allow services running on a host to authenticate
> themselves to the Key Distribution Center (KDC). Before a server can be
> setup to use Kerberos, the user must setup a keytab on the host running
the
> server. Note that any updates made to the keytab using ktab do not affect
> the Kerberos database. If you change the keys in the keytab, you must also
> make the corresponding changes to the Kerberos database.

the

for
> Solaris 8, see kadmin reference page.
