Right, Jason. It is not just Bill. I need Undertow as my embedded web
container for junit testing. Currently I use Jetty.
Apart from the standard security mechanisms in Undertow, I need the
ability to plug in my custom security stuff into UT in a junit environment.
Coming back to Darran's email, please see inline.

One thing I want to stress, is that Undertow was intended to be
usable as a standalone project, and it should be possible for someone like Bill to develop
an OAuth solution on it that he can run through a unit test. It's perfectly reasonable
to have certain advanced features be AS only, but the project itself still needs to
provide support for security.
This could very well mean we have a few duplicative SPIs, but as long as we do not have a
performance penalty and they don't prevent the use of proper AS integration I just
don't see a problem with them.

A simple IDM API in Undertow should be ok as long as there is an ability to
replace the IDM implementation with something more extensive (such as
via API calls on Undertow. Wildfly can then use the same Undertow API to
replace IDM default impl.
From PicketLink perspective, maybe we can provide some form of a driver
that users can use to install PL IDM in Undertow. This driver will be
bridge between UT IDM API and
PL IDM API.
