Squid Proxy report + captive portal user

[aries]

hi,

just want to ask if it is possible to generate proxy report that will include the captive portal username (from the local user manger) instead of the IP of the client. I have read that it is possible if I use squid authentication but since I am implementing captive portal it is nice if proxy reports will be tabulated against their username. hope I dont ask to much.  ;)

thanks :)
