[squid-users] user management

To all,

I'm running squid with fully integrated ldap authentication to AD, which
gives me good management and control of user authentication and access,
however, as the number of authorized users is growing I would like to
monitor how long each user spends on the web. I have full user login
logged in the access.log file.

Are there any application that would do that for me or is it just
getting my head down and writing it myself. Any help or direction would
be apprecitated.
