[squid-users] Squid Forward Proxy for LDAP

[Bryan Peters]

My Google-fu seems to be coming up short.

We have an application that ties into our users SSO/LDAP servers.  We,
don't run an LDAP server of our own, we're just making outbound calls to
their LDAP servers.

I would like to proxy all outbound LDAP calls through Squid to get around
some limitations of AWS and our customers need to whitelist an IP. (AWS
load balancers don't have static IPs, some of our customers won't whitelist
FQDNs in their firewall).

Getting the traffic from our app server(s) to the Squid box hasn't been
much of a problem.  I'm using Iptables/NAT to accomplish this.   TCPdump on
the Squid machine sees  traffic coming in on 3128.

I've added 389 as a 'safe port' in the squid config, created ACLs that
allow the network the traffic is coming in on.  Yet squid never grabs the
traffic and does anything with it.  The logs don't get updated at all.

Am I incorrect about Squid being able to proxy LDAP traffic?

Googling for this is sort of maddening as all forums, mailing lists, FAQs
and documentation continues to come up for doing LDAP auth on a Squid
machine, which isn't what I'm looking for at all.

Any help you can give would be appreciated.

Thanks
