Accessing an unprotected area triggers our custom
AuthenticationMechanism. Is this by design or by spec mandate? Or a bug?

I guess I should say, accessing a URL not protected by a
security-constraint still triggers our custom AuthenticaitonMechanism.

This is by design. Basically authenticate() will always be called, but sendChallenge()
will only be called if authentication is actually required, or if the user supplied
credentials that were actually invalid.
Basically the thinking is that is is better to authenticate, so if you are logging
requests or whatever you can see who is actually performing them.
Is this causing you problems? Originally we had a way to disable this behaviour, but it
seems to have been lost along the way.

The option should still be there although we may not be exposing it.
Just finishing off some CLI tasks and I am hoping my next task will be
to complete the authentication mechanism config that I discussed of
various lists quite a while back now.
This option should be a part of that.

sendChallenge is still called.

That should only be happening if the mechanisms indicated during the
authenticate step that it wanted a challenge to be sent.
As an example the DIGEST mechanism may want to do this if it receives a
stale nonce.

What is the indication? Sending back NOT_AUTHENTICATED?
As an example the DIGEST mechanism may want to do this if it receives
a
stale nonce.

The problem is my oauth mechanism has no way to know if there is another
mechanism or if the request is even supposed to be authenticated. If
there is not appropriate information in the request, it sends back
NOT_AUTHENTICATED and performs a redirect to the auth server in
sendChallenge.
Maybe I'm just using the SPI wrong. I'll take a look at Basic auth again.

If the required tokens were not within the message then the mechanism
should return NOT_ATTEMPTED.
If there are multiple mechanisms (or even a single mechanism) and
authentication is required but all the mechanisms return NOT_ATTEMPTED
then Undertow will take the decision to turn the request around and call
sendChallenge on each of them.
NOT_AUTHENTICATED means the mechanism saw 'something' in the incomming
requets and attempted to authenticate it but for some reason failed so
the message flow needs reversing and the challenges sending. This could
happen as an example if stale nonce is received in DIGEST.

Awesome. I misinterpreted how to pass back Outcomes. Returning
NOT_ATTEMPTED at the appropriate time seemed to fix this problem. I'll
close the JIRA.

Design but it can be disabled, we may still need to expose the option
however.
There are two reasons for this: -
1 - Authentication mechanisms based on mechanism specific processes
once authentication has commenced, e.g. DIGEST where the nonce count is
incremented on each request or the client or server are signing the request.
2 - Regular user demand that the authenticated identity is available
to the web app even when the non secured resources are accessed.
