Hi! I'm using Squid 3.1.15 with NTLM auth (SSO) for Active Directory on Windows 2003. NTLM SSO works perfect with Windows and Linux clients. Linux with Samba and Winbind (security = domain). Now I must work with Likewise. I follow this how to: http://www.beyondtrust.com/Technical-Support/Downloads/files/pbise/Manuals/likewise-samba-guide.html Using Ubuntu 11.04 and Likewise Open 6 (not apt). The system auth is perfect, but when the client open the browser it asks for user/password. Anyone integrates Likewise Open and Squid NTLM auth? Regards, Rodrigo. M.
