I did a clean install to version 1.3.1.Final and I am getting several 404.

I am  using : Wildfly 9 RC2, keycloak-overlay-1.3.1.Final.tar.gz

For instance:

Menu > Clients

Menu > Roles > Add role

GET https://localhost:8443/auth/admin/realms/myrealm/clients-by-id 404 (Not Found)

Menu > Sessions

GET https://localhost:8443/auth/admin/realms/myrealm/client-by-id-session-stats 404 (Not Found)
