I'm starting with OpenId using the dotnetopenid library and, so far, so good, but when I try to login, it shows me the following message:
This message has already been processed. This could indicate a replay attack in progress.
The first time I used my app it failed and, after that, the above message it is always returned.
How can I "logout" the user that I'm using for testing or how can I can clear the request so I can login/logout?
Thanks in advance! =)
I found the problem, a seely problem as usual...
I was calling the GetResponse more than once, and that got me error message.
Sorry for the inconvenience and thanks for your answers =)
