The "best" way to create a keytab is to randomize the password and use kadmin
to extract the keytab.

If you have a heimdal kdc, you can extract the keytab w/o changing the
The last time I looked the MIT code essentially randomized the
password and updated
the key when you created a keytab via the kadmin interface.

If you have the MIT version of the ktutil command, you can use that to
create a keytab
if you know the password. However, you have to also know the key version number
as well. ( kadmin should tell you this )

ktutil is kind of a weird interface, the command you want is add_entry.

Exactly what you do depends if you need to keep the password for use
by humans or not.

Once you have a keytab, k5start should allow you to do all the things you need.
