Re: [squid-users] LDAP in access.log

Sorry, missed the "key point":

>> I don't authenticate, and I can't enable it.

Now, the question is: where does he stores the "ldap authentication"
+ IP.... I don't get what is Riley trying to do.

Where does the users "log into"?. Anywhere they log into, that system
should be able to log the IP and the username, and then, another
(external) script could parse both logs files (which are on the same
computer, and thus can be time-correlated) and get squid's entries
coming from the same IP at the same time as the user was logged in
from that IP.... but then, there are some ISPs (mostly, cell phone
access), that masquerade their users to a narrow set of *real* IPs,
and thus: you can have more than one user at the same time from the
same IP (at least, that's possible).

I hope this helps,
