Hi Pedro,
I'll let Jim follow-up on the details here and see with you the best way to
move forward.
This said, in the current scenario, the isValid is method is not called (it
was originally thought for the username token profile scenario, so the
string password credential would be available, etc), maybe it should be
changed a bit to be used in this scenario too, so that the pushContext is
not needed, according to what you're writing below.
Can you and Jim please review the current implementation of
ElytronSecurityDomainContextImpl and change it to support this SAML token
authentication scenario too?
Thanks
