this controller :

[childactiononly]         public actionresult logedinuser()         {             var user = new userviewmodel();             if (request.isauthenticated)             {                 user.nom_user = user.identity.name;             }             return partialview(user);         } private gammecontext db = new gammecontext();         [acceptverbs(httpverbs.post)]         [system.diagnostics.codeanalysis.suppressmessage("microsoft.design", "ca1054:uriparametersshouldnotbestrings",             justification = "needs take same parameter type controller.redirect()")]         public actionresult logedinuser(string matricule, string password, bool rememberme, string returnurl)         {             if (!validatelogon(matricule, password))             {                 return connection(matricule, password, returnurl);             }              //formsauth.signin(matricule, rememberme);              if (!string.isnullorempty(returnurl))             {                 return redirect(returnurl);             }             else             {                 return redirecttoaction("index", "home");             }         }          public actionresult connection(string matricule, string password, string returnurl)         {             list<user> users = db.users.tolist();             actionresult output = null;              if (users.any())             {                 foreach (user u in users)                 {                     if ((u.matricule == matricule) && (u.password == password))                     {                         output = view();                     }                 }             }             else             {                 output = redirect(returnurl);             }              return output;         } 

i don't see you're authenticating user ? if try this:

if (!validatelogon(matricule, password)) {           return connection(matricule, password, returnurl); }  // user valid, authenticate formsauthentication.setauthcookie(matricule, true);
