Sounds like the simplest thing to do is turn on authentication on all
the boxes and allow then non auth access to each other

Ta, i will have to have a read, does it work. any examples on how to setup?

what if I just want the authenticated user id to flow through. So the
authentication happen on the office squid and then it forward to the
DC squid, the dc squid can log the user name in the user field is that

Is there a way to say any one attaching on port X doesn't need to be
authenticated but on port Y does.
My issues is that in the office I have a few eclipse users who had a
lot of problems with out previous proxy solution. they are setup to
use the office proxy in a nonauth way. but now I want to setup auth on
this squid box. I was thinking there could be a non auth port and a
