<span style="color:#222222; font-family:Segoe UI,Tahoma,Arial,Helvetica,sans-serif; font-size:13px; background-color:#f0f3f4 Then I also have the following code in global.asax
<pre class="prettyprint Protected Sub Application_AuthenticateRequest(sender As Object, e As System.EventArgs)
If HttpContext.Current.User IsNot Nothing Then
see if this user is authenticated, any authenticated cookie (ticket) exists for this user
If HttpContext.Current.User.Identity.IsAuthenticated Then
see if the authentication is done using FormsAuthentication

If TypeOf HttpContext.Current.User.Identity Is FormsIdentity Then
Get the roles stored for this request from the ticket
get the identity of the user

Dim identity As FormsIdentity = HttpContext.Current.User.Identity
get the forms authetication ticket of the user
Dim ticket As FormsAuthenticationTicket = identity.Ticket
get the roles stored as UserData into the ticket
Dim roles As String() = ticket.UserData.Split(",")
HttpContext.Current.User = New System.Security.Principal.GenericPrincipal(identity, roles)
End If
End If
End If
End Sub[/code]
