This is sample of LiveID login. Application uses special settings for domain mydomainxy.com. To make this example work you must edit your hosts file to redirect mydomainxy.com to 127.0.0.1, add same domain alias to sample Corporate Site, install Kentico into virtual directory named KenticoCMS and you must not be signed in (control is hidden). Basically you need to make accessible the return URL (http://mydomainxy.com/KenticoCMS/CMSPages/LiveIDlogin.aspx) or register your own domain for the Live ID services. You will need to ask our support for community license key for mydomainxy.com. For more information see the documentation.
