Role & froms authentication

[Lloyd Dupont]

I'm trying to setup a very simple form authentication in my WebApp (a few
user in an XML file).
I'm also trying to use the Role in my application.

I don't want to use a database.

I'm trying to call Rolls.AddUserToRole(username, role)
but I get an exception: ProviderException

what could I do?
