I am using keycloak and have assigned some global roles (TOUPPER and REVERSE) to a user.  The decoded access token looks like this...

        {
  "jti" : "0a0541f2-9b74-4a41-b862-a20a3cbc2bcb",
  "exp" : 1464097823,
  "nbf" : 0,
  "iat" : 1464097523,
  "iss" : "https://my.keycloak.com/auth/realms/TenantA",
  "aud" : "test-client",
  "sub" : "20974f13-8272-4cd5-a172-5c8de4cdc782",
  "typ" : "Bearer",
  "azp" : "test-client",
  "nonce" : "C_D0xDSCytoFaopJoYZu36BJcb6eMR2Xeg8VGP2nxeQ",
  "session_state" : "b625d171-e01d-462c-9d01-d159b9b75635",
  "name" : "",
  "preferred_username" : "anthony",
  "client_session" : "80b0ac34-5ee8-41f2-97da-649cf1abbd81",
  "allowed-origins" : [ ],
  "realm_access" : {
    "roles" : [ "TOUPPER", "REVERSE" ]
  },
  "resource_access" : { },
  "groups" : [ "tenantA/brandA", "tenantA" ]
}


I'm now trying to configure mod_auth_openidc authorization on some url paths based on the roles in the "realm_access"."roles" path of the token.  I've tried this configuration...

        <Location /glomex-mds-webapp/api/v1/secure/demo/toupper>
                AuthType openid-connect
                #Require valid-user
                Require claim realm_access.roles:TOUPPER
        </Location>

This doesn't seem to work though.  Is it possible to use json path syntax for claim authorization?
