 Ident(d) may work for you. Squid can use ident for identification, and if
you are running it on your LTSP server then the TCP connections are
identified by the correct user ids.
 I have to add that Ident is not safe
1) It can easily be spoofed.
2) Transmits valid user ids so it can make it easier for someone to hack
your system.
3) May be vulnerable to buffer over/under run attacks
 So if you do use Ident make sure that your LTSP server is on an intranet
that is protected by a firewall, also make sure you don't broadcast ident
responses to people outside of your intranet or people you don't trust.
