Sorry for not being clear. As Walt Tuvell later stated - the answer is YES.
An application that is unaware of the DCE and uses a client Kerberos
library can communicate with a DCE security server over UDP port 88 using
the protocol defined in RFC 1510. The DCE security server listens in the
"standard way" to requests coming from outside the DCE world.

DCE vendors do not currently advertize this since there isn't a validation
suite for the RFC 1510 protocol. We expect that subsequent releases of the
DCE will more fully test this protocol - fix any bugs found - and will then
advertize this support.

The answer to your next question is yes, the DCE AS and TGS services
maintain keys in the DCE Registry (which, in the current imlementation, is
the database co-located with the services).
