Dear James, Thanks for the attention. Yes, I´m talking about Debian APT Tool =]. And I´ve already configured apt.conf so to use the proxy, adding username and password in it, but even so it´s not working, and my proxy keeps returning HTTP 407. Tried creating a user "me" with password "123456" inside my AD domain, and it´s not working as well. Maybe something in my Squid auth configuration, but I´m not sure. 2009/2/2 James Zuelow <James_Zuelow@xxxxxxxxxxxxxxx>: > >> -----Original Message----- >> From: Henrique Machado [mailto:henrique.cicuto@xxxxxxxxx] >> Sent: Monday, 02 February, 2009 06:49 >> To: squid-users@xxxxxxxxxxxxxxx >> Subject: Certain applications when using NTLM auth > >> But, some applications, APT being a very simple example (and one of my >> headaches) can´t ask for an input.

I have a variety of Debian boxes (used to be Sarge, now Etch and Lenny) that authenticate to squid via NTLM, and this "just works" for me: > > Set up an /etc/apt/apt.conf file like this: > > Acquire::http::Proxy "http://username:password@xxxxxxxxxxx:3128/"; > > Where username and password are for a service account you create in active directory. You can use a human's account, but the password will be in plaintext with the apt.conf file, so I don't suggest it. Easier to create a service account and then just tightly lock it down in AD.
