I am running

squid 3

Squid is my proxy for Windows clients in an Active Directory Domain. I have this setup so that it authenticates users transparenlty.
When browsing my squid log "access.log" I can see data being generated and usernames from AD.

When using sarg to generate reports, under the colum "USERID" all I am seeing is the IP address and not the AD username. Does anyone know how to correct this so it displays AD usernames instead.
