Unable to propagate security context using IIOP between two AS7 server instances

Because AS7 uses the SASClientIdentityInterceptor it expects that the security context will be propagated using a trust based mechanism, however this trust based mechanism has not actually been fully implemented.

In EJBCorbaServant there is some code that comes from AS6 that just assumes username=password, with a comment that this needs to be removed once we have a mechanism to establish trust.

For now I think that we need to do two things:

• Allow the server to easily use the SASClientInterceptor
• Use the SASCurrent as a credential in EjbCorbaServant, so a custom login module can be used to establish trust
