Hi guys
I've managed squid to work with AD, and authorize users based on what AD group they are in. I use Squid-Analyzer for doing reports from access.log. I've found 2 anomalies with authorization so far. In access log, I see that user is authorized based on his PC name(not desired) and not on the user account name. I've just enabled debugging on negotiate wrapper, so I will monitor these logs also.
But in the meantime, have you got any idea why could this happen ?
