I try to integrate a forum in a existing .net MVC website.

For now I don't want to merge the authentication. I use the MVC authentication for the website and the default YAF authentication on the forum.

https://github.com/YAFNE...ting-ASP.NET-Application 

My problem is that it seems I can log in (I enter my login and my password and I haven't error message), but when I am redirected on the homepage I'm not connected.

Do you have an idea to solve this problem ?

Well if yo dont merge the authentication then of course it can't work together and you have to login separately.
