Stian,

A follow-up on realm resources - I've stumbled upon this thread: http://lists.jboss.org/pipermail/keycloak-dev/2015-December/006100.html

That "(coming) ability to freely extend the JPA entities and DB schema" is the very same Entity SPI you were talking about, right?

Yep
 

I see now how to implement realm resources. It's a pity that custom
admin resources (initially included into Pedro Igor's commit) were
removed; these would be a fairly natural addition to the upcoming
Entity SPI. Are there any plans to include that back?

We plan to add it, but we'd like it to have some support for authorization, which the PR didn't provide. So there was basically no difference between the two in the original PR.
 

As a workaround, is it possible to install a custom realm resource
(/realms/{realm}/foo), manually protect it with an authorization
constraint, and use it inside admin console (as a surrogate admin
resource)?

Yes, that's fine. You can look at the source code for how we deal with authorization in the admin resources. Look at AdminRootResource I think it is.
 

Cheers,
Mitya

P.S. BTW, examples/providers/rest/pom.xml contains an erroneous "<name>Authenticator Example</name>" inside
