Subject RE: Hot deployment

I was thinking of using the Generic Connector.  This would allow for the
automatic injection of the Subject into the communication circuit from
the Geronimo security environment.  We could also benefit from many of
the other features provided by the Geronimo network stack.

Especially for security, some level of generalization about
authentication may be achieved with SASL and user input, but I see that
quite complex.

If you hard code in the client that authentication uses a password, then
if you have a communication protocol that supports also certificates you
may not be able to use certificates.
OTOH, if you hard code the certificate as credential, simpler protocols
may not support that kind of authentication.

JSR 160 authentication with RMI is pluggable (via a JMXAuthenticator).

I may be wrong (still my knowledge of Geronimo is very low) but a
suitable JMXAuthenticator may fit the need of having a single point
where credentials are defined.
