Hi Colm
Sounds great. But where do I get the "securityContext" from in my validator?
And who has it created? Another interceptor that is called earlier?
Thanks
Stephan

An alternative could be to set the principal on the returned Credential object
in your validator, for example:
credential.setPrincipal(securityContext.getAuthentication().getPrincipal());
CXF will use this to set up a SecurityContext object which returns this
principal via "securityContext.getUserPrincipal()". This is stored in the
current message via the key "SecurityContext.class" so you could retrieve this
object in your interceptor and extract the principal from it.
Colm.
