[squid-users] ident_lookup_access confusion

I'm trying to log userids from users on a linux terminal server on our squid
server. I've just compiled a fresh squid-2.5.STABLE1 and made sure I did not
use the --disable-ident-lookups flag on configure. However, including the
following in my squid.conf does not provide the expected results:

acl ltsp src 10.168.12.235/255.255.255.255
ident_lookup_access allow ltsp
ident_lookup_access deny all

I've used a packet sniffer on the squid box and I do not see a request being
made on port 113 at all, so it appears that squid is not generating the request.

Looking through google I found the following suggested additional config to
try to force ident lookups:

acl test ident REQUIRED
http_access deny test !all

This does not seem to help either. Any ideas would be greatly appreciated!
