            if (authCookie != null)
            {
                FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
                if (authTicket != null && authTicket.UserData != null)
                {
                    var rehauIdentity = new RehauIdentity(HttpContext.Current.User.Identity) {AccountType = authTicket.UserData};
                    HttpContext.Current.User = rehauIdentity;
                }
            }
        }

//IdentityClass

public class RehauIdentity : IPrincipal
    {
        public IIdentity Identity { get; private set; }
        public bool IsInRole(string role) { return Roles.IsUserInRole(Identity.Name, role); }
        public RehauIdentity(IIdentity identity) { this.Identity = identity; }
        public string AccountType { set; get; }
    }
