I've configured 2 zones in sharepoint 2013. Both zones are configured to use NTLM and FBA authentication in order to have full availability of all users in the people picker.
My extranet zone (FBA) has custom sign in page set to /_forms/default.aspx... which works a treat with both fba login and people picker behaving as required. Configuring my intranet zone (NTLM) to use the default NTLM login URL /_windows/default.aspx... causes it to return an application runtime error. I understand that if I create a custom login page for NTLM I should be able to present my intranet users with transparent login. Is there anyone able to provide pointers on how to set up a custom page for NTLM?
I've found this post (http://tomaszrabinski.pl/wordpress/2011/06/23/sharepoint-2010-custom-login-page/) which is exactly what I need but have been unable to implement it for SP2013. Any help would be greatly appreciated. I'm not a coder but have given it a go in vs2013 using zavaz code. Changed the identity model reference and got the solution deployed to my test site butt getting server block errors etc. Gonna keep working through it. If I eventually get sorted I'll post my findings.
