Subject: Re: [undertow-dev] figuring out how to integration resteasy oauth
I have an added problem here of having to provide configuration for
this. (i.e. keys).

I don't think you actually need a custom identity manager, your mechanism can just
create a new Account
and pass it to the SecurityContext.authenticationComplete() method.

What you can do here is provide a io.undertow.servlet.ServletExtension implementation
(with a META-INF/services entry).
This allows you to modify the deployment before boot time, so you can check for the
presence of a custom configuration file (e.g. jboss-oauth.xml or whatever),
and if it is present modify the deployment accordingly, adding your authentication
mechanism, and possibly any additional handlers etc that you need.
At some point soon we will probably provide some way of configuring additional mechanisms
declaratively in jboss-web.xml as well, but that basically limits you to just
installing a mechanism and configuring via key value properties.
The trickier problem is the JAAS Identity Manager. This was always intended to be
temporary, but I really doubt that PL IDM will be replacing JAAS so I think we might be
stuck with it.
Because this was intended to be temporary there is some additional functionality in the
IDM that does not really belong there (namely it modifies the picketbox security context,
and pushes the principal vs role map thread local). I will have a look at this today and
try and clean this up a bit.
