[Samba] mod_auth_ntlm_winbind + IE problem

Hi there,

I'm having problems with the mod_auth_ntlm_winbind module. 
Background: 
- Apache 2 server running on Fedora 4. 
- Computer is a member of the domain (security = ADS)
- The authentication seems to work fine, I can access shares, wbinfo -u/-g 
returns a valid output, etc.

The authentication is enabled in Apache for a specific folder only.

<Directory "/var/www/html/confprod/v2" >
  AuthName "NTLM Authentication thingy"
  NTLMAuth on
  NTLMAuthHelper "/usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp 
--debuglevel=10"
  NTLMBasicAuthoritative on
  AuthType NTLM
  require valid-user
</Directory>

My problem is that IE gives me an error page when I try to access the 
pages from that folder. I have enabled all the logging I could find but I 
can't find something that looks like a real error message. 

Can I enable more logging? Is there anything else to configure other than 
samba, apache, PAM and winbind?

Here is an abstract of the httpd/error_log. 

Any help will be greatly appreciated.

Best regards,
Laurent
