Thanks for the comments.

I did not read the source sufficiently to be able to estimate how much
Kerberos provides for additional security - glad if Coda is at the same
level.

But anyway it would be nice to be able to use the same authentication
server and database for other services besides Coda.

Hopefully at some place outside USA somebody will fund adding
strong encryption and Kerberos authentication to Coda.

( fortunately, it is allowed to import :)

Anyway, exportable description of the routines and their intended purpose
would be very welcome.

Regards,
