Trying to use openid4java against Yahoo. Google's system is working fine, however with Yahoo, I'm getting

Verification failed for: https://me.yahoo.com/a/ [random string] reason: Direct signature verification failed.

I've gone through this blog:
http://eddevelop.blogspot.com/2008/11/open...penid4java.html

And those linked there. I have my XRDS setup correctly, and Yahoo no longer complains about an invalid website -- everything looks good there..

However, when the request comes back, I get that Direct signature verification failed message, and VerificationResult.getVerifiedId() returns null.

Help?
