Method Detail

### authenticate

    public Principal authenticate(UserRealm realm,
                                  String pathInContext,
                                  Request request,
                                  Response response)

  Description copied from interface: `Authenticator`
  Authenticate.

  Specified by:
    `authenticate` in interface `Authenticator`
  Parameters:
    `realm` - an `UserRealm` value
    `pathInContext` - a `String` value
    `request` - a `Request` value
    `response` - a `Response` value. If non-null response is passed, then a failed authentication will result in a challenge response being set in the response.
  Returns:
    UserPrinciple if authenticated or null if not. If Authentication fails, then the authenticator may have committed the response as an auth challenge or redirect.
  Throws:
    `IOException`

### getAuthMethod

                       throws IOException

  Throws:
    `IOException`

### newNonce

    public String newNonce(Request request)

### checkNonce
