Ah, clear. Thanks a lot! That is exactly what we were looking for.

You deploy that jar, and it should work.  Again, there is documentation for other SPIs, packaging would work the same for protocol mapper.

We really only want to build our custom mapper and somehow add it to the Keycloak distribution if at all possible. The Java class is the easy part I guess, but adding the mapper definition to the META-INF file seems a little harder.
