DotNetOpenAuth Issue with Yahoo!

I use OpenID authentication and all of the providers have been tested and work fine when running the website from Visual Studio. I have deployed the website to the server and the Google and myOpenID work just fine but Yahoo! OpenID provider just throws this error...

The OpenID Provider issued an assertion for an Identifier whose discovery information did not match. Assertion endpoint info: ClaimedIdentifier: https://me.yahoo.com/a/KyzgPcp9v8xRcWxFNKx357hQTxZ9P7Udww8bPkpv3oNSoogH0IXw#11950 ProviderLocalIdentifier: https://me.yahoo.com/a/KyzgPcp9v8xRcWxFNKx357hQTxZ9P7Udww8bPkpv3oNSoogH0IXw ProviderEndpoint: https://open.login.yahooapis.com/openid/op/auth OpenID version: 2.0 Service Type URIs: Discovered endpoint info: [{ ClaimedIdentifier: http://specs.openid.net/auth/2.0/identifier_select ProviderLocalIdentifier: http://specs.openid.net/auth/2.0/identifier_select ProviderEndpoint: https://open.login.yahooapis.com/openid/op/auth OpenID version: 2.0 Service Type URIs: http://specs.openid.net/auth/2.0/server http://specs.openid.net/extensions/pape/1.0 http://openid.net/srv/ax/1.0 http://specs.openid.net/extensions/oauth/1.0 http://specs.openid.net/extensions/ui/1.0/lang-pref http://specs.openid.net/extensions/ui/1.0/mode/popup http://schemas.xmlsoap.org/ws/2005/05/identity/c开发者_高级运维laims/privatepersonalidentifier http://www.idmanagement.gov/schema/2009/05/icam/no-pii.pdf http://www.idmanagement.gov/schema/2009/05/icam/openid-trust-level1.pdf http://csrc.nist.gov/publications/nistpubs/800-63/SP800-63V1_0_2.pdf },]

If anyone has any idea why this is happening I would really appreciate it. This only occurs on the server so I can't debug it easily.

Thank You.

This suggests that your RP is performing discovery on the original identifier ("yahoo.com") instead of the claimed identifier in the assertion. Can you activate logging and include the entire surrounding log from the server in your question?
