As I understood it, it is the task of the client side. Kerberos 4
principals are restricted to the form of "pricipal" or
"princ.instance".  So if aklog (or any other client program) wants to
get an afs token, it has to translate the krb5 principal to the krb4 form. 

For usual human users with principals without any dots and slashes
such as "schulz", nothing changes. Principals such as "schulz/admin",
need to be translated to "schulz.admin". It really gets tricky when it
comes to principals such as the above mentioned
"host/name.of.machine.domain". This gets translated to "rcmd.name" by

mini-faq on my web-page.... or does anybody already started to do so?
