# OAuth2RBAC 

###
Companion object OAuth2RBAC

#### class OAuth2RBAC extends AnyRef

Functional interface that allows users to implement custom RBAC verifiers for OAuth2/OpenId Connect.

Users are to implement the `isAuthorized` method to verify authorities. For provides that do not export the permissions/roles in the token, this interface allows you to communicate with 3rd party services such as graph APIs to collect the required data.

The contract is that once an authority is checked for a given user, it's value is cached during the execution of the request. If a user is stored to a persistent storage, or the token is introspected, the cache is cleared and a new call will be handled to the implementation.

    This method should verify if the user has the given authority and return either a boolean value or an error.

    This method should verify if the user has the given authority and return either a boolean value or an error.

    Note that false and errors are not the same. A user might not have a given authority but that doesn't mean that there was an error during the call. * @param user the given user to assert on

    authority

      the authority to lookup

    handler

      the result handler.

13.  def isAuthorizedFuture(user: AccessToken, authority: String): Future[Boolean]

    Like isAuthorized but returns a scala.concurrent.Future instead of taking an AsyncResultHandler.
