Re: [squid-users] Need help in integrating squid and samba

Dear Christopher,

Thank you for your reply.

I am not using Active Directory, I am using a samba as a PDC (NT4) and
its a simple configuration. All clients are WinXP and they login to
the domain and i just want to control their access to internet that is
all.

And there is no other Windows NT domain machine in my network, its
just this ubuntu server running squid and samba!

If i am right? wbinfo -t will not work coz, i don't have a windows NT
domain machine and no trust exists. But, how do i control, restrict or
allow internet access for samba domain users through squid?

Many Thanks
Avinash
