Correct Active Directory code to retrieve a key field

I am using VS2017 and trying to retrieve the username from the active directory of my school district.  Below is my syntax.

if (userName != " ")
                KatyISD.Library.ActiveDirectory.User user = new KatyISD.Library.ActiveDirectory.User(userName);

                Response.Cookies.Add(new HttpCookie("KUId", user.Guid));
                Response.Cookies.Add(new HttpCookie("userNetworkID", user.UserName));
                Response.Cookies.Add(new HttpCookie("userName", user.LastName + ", " + user.FirstName));


Is the code correct?
