This could mean two things: Either the requested service is unable to
retrieve it's own service key from the srvtab file (have you
remembered to create a srvtab file with a service entry for
kpasswdd??), or it is not able to decrypt the ticket/authenticator
pair received in the request packet, probably because the ticket or
authenticator were not encrypted with the service key. The service key
in the srvtab file may not be the same as the one in the kerberos
database (do an ext_srvtab). 

There is a last possibility that I encountered som time ago: you link
your programs with different (incompatible) des-libraries.

BTW: comp.protocols.kerberos might be the most appropriate group for
questions regarding Kerberos.
