Session dependency bug

Hi, in the connector ACL code there is a session dependency that causes an '[OK] message' failure.
Haven't investigated well, but the code below fixes my problem...

// Get the user role from the session.
string userRole = null;
if ( ConfigFile.Current.RoleSessionVar.Length > 0 && System.Web.HttpContext.Current.Session != null)
userRole = System.Web.HttpContext.Current.Session[ ConfigFile.Current.RoleSessionVar ] as string;
if ( userRole != null && userRole.Length == 0 )
userRole = null;
