DotNetOpenAuth: Message signature was incorrect
- by Shawn Miller
I'm getting a "Message signature was incorrect" exception when trying to authenticate with MyOpenID and Yahoo.
I'm using pretty much the ASP.NET MVC sample code that came with DotNetOpenAuth 3.4.2
public ActionResult Authenticate(string openid)
{
var openIdRelyingParty = new OpenIdRelyingParty();
var authenticationResponse = openIdRelyingParty.GetResponse();
if (authenticationResponse == null)
{
// Stage 2: User submitting identifier
Identifier identifier;
if (Identifier.TryParse(openid, out identifier))
{
var realm = new Realm(Request.Url.Root() + "openid");
var authenticationRequest = openIdRelyingParty.CreateRequest(openid, realm);
authenticationRequest.RedirectToProvider();
}
else
{
return RedirectToAction("login", "home");
}
}
else
{
// Stage 3: OpenID provider sending assertion response
switch (authenticationResponse.Status)
{
case AuthenticationStatus.Authenticated:
{
// TODO
}
case AuthenticationStatus.Failed:
{
throw authenticationResponse.Exception;
}
}
}
return new EmptyResult();
}
Working fine with Google, AOL and others. However, Yahoo and MyOpenID fall into the AuthenticationStatus.Failed case with the following exception:
DotNetOpenAuth.Messaging.Bindings.InvalidSignatureException: Message signature was incorrect.

Appears that others are having the same problem: http://trac.dotnetopenauth.net:8000/ticket/172
Does anyone have a workaround?
