Have you verified that the server password in the KDC is the same as
the one in your srvtab? I have experienced "Cannot decode
authenticator" errors when I have changed one, but forgot to do an
ext_srvtab. When the server tries to learn the session key from the
ticket, using the srvtab password, it fails (because they are
different) and thus fails to decrypt the authenticator.
