I've a 7.5 IIS installed on my server with windows authentication enabled because I need it for NTLM / SSO on intranet pages.
When windows authentication is activated, IIS can't authenticate itself on it's own webserver.
This is the error I get in the IIS log:
2011-11-24 08:47:10 10.50.2.91 POST /ldap.php - 80 - 10.50.2.91 SWIFT_LoginShare 401 2 5 0
So, how can I make sure, using windows authentication, that IIS authenticates itself?
