  • Please check the answer I have given in above link, I believe you have the same issue, and you can solve it with changing the cookie name on authentication on web.config. – Aristos May 15 '13 at 17:15

Ensure that both web applications are using the same machineKey values in the web.configs. This is used for encryption/decryption of the forms authentication ticket. There is really good information here: http://msdn.microsoft.com/en-us/library/eb0zx8fc(v=vs.100).aspx
