I use membership provider

after i validate the user using

Membership.ValidateUser(userName, pass)

I use

FormsAuthentication.SetAuthCookie(userName, True)

after if I call a function that has to use the username (its a method of a class)

and there I use

HttpContext.Current.User.Identity.Name returns

to get the name

and i get empty string

why?

(I use it a lot in my project and it works fine, only here, maybe because I just authenticated I have the problem)

thanks
