Hi Amos,
Sounds interesting.
Maybe I should modify the external_acl_type to talk with internal API
inside my system.
Can you please point me to some code examples and documentation?
Also if you can please point me to squid code that invokes the external
ACL program?
Thanks,
Ben

Not with just authentication. You will need to use a slightly more
complicated system involving an external_acl_type helper as well and
switch to an SQL database auth system.
The idea for that is that you have a database of authenticated users
with their last-known IP address.
Your auth_param helper is changed to one which takes client IP
address in the auth_param key_extras setting, and adds records to the
SQL database before telling Squid the login is OK.
Use an ext_sql_session_acl helper which takes IP address and checks
the database to find the username who last authenticated from there.
This needs to be checked and permit existing sessions before the auth
helper.
The config looks something like this:
external_acl_type ipuser negative_ttl=0 ttl=7200 %<a \
/usr/bin/squid/ext_sql_session_acl \
--dsn "..." --user dbUsername --password dbPassword --persist \
--usercol username --uidcol ipaddress
acl user_known external ipuser
http_access allow user_known
auth_param basic program /path/to/helper
auth_param basic key_extras %<a
auth_param basic credentialsttl 2 hours
acl authenticated proxy_auth REQUIRED
http_access allow authenticated
