Hallo: I'm trying to authenticate my Firefox(Linux) to Squid (Linux) using NTLM without having to type my domain/user and password. What I have: - Win2003 running IIS (Internet Information Server). - RedHat running Squid 2.6.STABLE14 - Client WinXP with IE and Firefox. - Clients Ubuntu 8.04 and OpenSuse 11.2 integrated with AD with Likewise (ubuntu) and Samba (Opensuse). What I've got: 1- IIS on Sever Win2003 and Client Firefox (Ubuntu 8.04 and OpenSuse 11.2): I can connect to Win2003 and I'm not asked for domain\username and password. NTLM works fine. 2- RedHat with Squid and Client WinXP (Firefox and IE). I can access a protected URL with authentication and I'm not asked for username and password. NTLM works fine, both Firefox and IE. What I've not got: 3- RedHat with Squid and client Ubuntu-Firefox When I try to access the same URL protected with authentication (trough squid), I'M ASKED for domain\username and password. If I type it, I'm allowed to access. What I want is not to be prompted, just extract it from my session, the same if the client were WinXp. For short: - IIS: I can use NTLM form Windows and Linux clients and it works fine. - Squid: I can use NTLM if client is Windows, but I'm asked to type domain\username and password if client is Ubuntu. Why do I have to type the domain\username and password if my client is Linux? What`s wrong?
