Recursive Page.FindControl

ASP.NET NTLM Authentication - is it worth it?

At work, we have the luxury of assuming that everyone’s on an intranet. So when it comes to identity management on our ASP.NET websites, NTLM authentication is the go-to solution. Why trouble the user with Yet Another Login Dialog when you can leverage the built in NTLM
