Hi Larry,

I'd like to change the logic of AbstractJWTFilter.validateAudiences + I'm
wondering what your opinions are on this. Currently the JWT + SSOCookie
filters take an expected audience (or audiences if a comma-separated String
was specified) name from a configuration parameter. When parsing a received
token this logic is followed:

a) If no pre-configured audiences then validation is fine
b) Otherwise if the token has an audience that matches one of our
pre-configured audiences then validation passes.
c) Otherwise validation fails.

I'd like to change this logic to take into account the request URL. This is
what the AccessTokenFederationFilter does, although it doesn't check for
pre-configured audiences. I'm thinking validation logic along the following
lines....

a) The received Token must have an audience that matches a pre-configured
audience if one is specified
b) If no pre-configured audience is configured, then the token must have an
audience that matches the request URL
c) Otherwise validation fails.

If you feel that point (b) is too strict, I could add a new boolean
configuration property to control whether to enforce the request URL
matching or not.

WDYT?

Colm.
