Hi, I am using Samba 3.0.5 version on Debian. Here is my requirement. User authentication should happen from my win2k ADS server. I configured as per help but I am not successful during authentication. I am able to get wbinfo -u , wbinfo -g & wbinfo -t commands successfully. Here is my configuration.
