I am relative newcomer to linux. I have an NT 4 based domain with squid server as a proxy to approx 500 users. I want to allow users to authenticate (hopefully) transparently to the NT4 domain so that most importantly the username will be logged to access.log and hence appear in SARG (we currently only monitor ip addresses). I am using Winbind with SAMBA and want to do something similar as i have heard this works with other services and do not want to maintain multiple account databases. Does anyone have any suggestions.
