Apache2::AuthenNTLM Failing Authentication from Vista Internet Explorer

[Je...@manerf.com]

Hi there,

I'm having problems with the NTLM Authentication against our 
ActiveDirectory. I set it up on my Apache2 and it works well with Firefox 
on Linux/XP/Vista with prompting for login.
It also works on latest Internet Explorer for XP (without prompting for 
login).

I'm always getting
[Sun Mar 11 09:30:25 2007] [error] Bad/Missing NTLM/Basic Authorization 
Header for /
in the apache log but as said it works.

What does not work is Internet Explorer for Vista. Here I am prompted for 
login and after entering it I get
[error] Wrong password/user ...
for any account I try to login with. As said logging in with Firefox with 
prompted login from the same system works well.

Any ideas? I thought IE7 on XP or Vista would make no difference but 
appearently it does...
