Comment 3 for bug 2018472

Thanks for reporting a bug and helping make Ubuntu better.

I tried to reproduce the problem here, but I think I'm missing something. Maybe you could help me figure it out.

First, I set up squid inside a Jammy container and added the following lines to /etc/squid/squid.conf:

auth_param basic program /usr/lib/squid/basic_ncsa_auth /etc/squid/private/USERS.internet_plain
acl ncsa_users proxy_auth REQUIRED
http_access allow ncsa_users
http_access deny all
acl users_unlim proxy_auth test
delay_pools 1
delay_class 1 1
delay_parameters 1 1024/1024
delay_access 1 allow users_unlim
delay_access 1 deny all

Then, I created the file /etc/squid/private/USERS.internet_plain and added the "test" user to it:

# htpasswd -b /etc/squid/private/USERS.internet_plain test test

I restarted the service, then created another container and tried to use curl with the proxy. Here's what I'm getting:

# curl -vvvv -x test:test@10.96.142.20:3128 example.com
* Trying 10.96.142.20:3128...
* Connected to (nil) (10.96.142.20) port 3128 (#0)
* Proxy auth using Basic with user 'test'
> GET http://example.com/ HTTP/1.1
> Host: example.com
> Proxy-Authorization: Basic dGVzdDp0ZXN0
> User-Agent: curl/7.81.0
> Accept: */*
> Proxy-Connection: Keep-Alive
>
* Empty reply from server
* Closing connection 0
curl: (52) Empty reply from server

When I look at the squid logs, I see that apparently the basic_ncsa_auth script wasn't invoked:

Could you please take a look at what I did and let me know if there's anything missing?

I will mark this bug as Incomplete in order to make it clear that we're still missing some reproduction steps. Please mark it back to New once you provide the require info. Thanks.
