* Test redirect_uri construction This was a test marked as TODO. * Remove duplicate test * Add tests to exactly match redirect URIs * Redirect URIs must match exactly. To quote from the specification at http://openid.net/specs/openid-connect-core-1_0.html#AuthRequest: Redirection URI to which the response will be sent. This URI MUST exactly match one of the Redirection URI values for the Client pre-registered at the OpenID Provider, with the matching performed as described in Section 6.2.1 of [RFC3986] (Simple String Comparison).
