Authenticate MembershipUser without password?

Question

Is it possible to authenticate a MembershipUser without a password. I have gues user accounts and whihc have temporary passwords, however i do not required these users to actually login. I want to automatically authenticate them back on their userid.

Can this be done?

FormsAuthentication.SetAuthCookie(publicuser.UserName, false); 

doesn't seem to actually authenticate them againsts the memebrship provider.

You can override the ValidateUser defined in System.ServiceModel.DomainServices.Server.ApplicationServices:

protected override bool ValidateUser(string userName, string password)

Then you can check

if ( IsAGuestAccount( userName ) ) return true;
