I have used the following url:
http://webApplication/_windows/default.aspx?ReturnUrl=%2f_layouts%2fAuthenticate.aspx%3fSource%3d%252FSitePages%252FHome%252Easpx&Source=%2FSitePages%2FHome%2Easpx to use my windows auth, but I cannot load the page, I have used custom Sign In Page /_layout/IMSA/default.aspx. How do I resolve this issue? I need windows authentication to see some of the administrative tool in the site setting page.
