            SPIisSettings iisSettings = SPContext.Current.Site.WebApplication.IisSettings[SPUrlZone.Default];

            //Retrive forms authentication provider
            SPFormsAuthenticationProvider formsClaimsAuthenticationProvider = iisSettings.FormsClaimsAuthenticationProvider;

            //Create forms token using forms authentication provider settings and login details
            SecurityToken token = SPSecurityContext.SecurityTokenForFormsAuthentication(new Uri(SPContext.Current.Web.Url),
                formsClaimsAuthenticationProvider.MembershipProvider,  //Set while creating/extending web application
