RE: Please help! problem chaining 2 proxies with authentication

Please don't send HTML mail.
http://www.squid-cache.org/Doc/FAQ/FAQ-10.html#ss10.7 if you see faq . you
will see:

FAQ: Only ONE proxy cache in a chain is allowed to ``use'' the
Proxy-Authentication request header. Once the header is used, it must not be
passed on to other proxies.

So if Both of your neighbour caches have authentication. they don't pass
authentication header from one to other. Either you should not use chain or
you should use authentication on only one proxy.

Subject: Please help! problem chaining 2 proxies with authentication

Dear squid admins,
We have to proxy servers ,Proxy A and Proxy B. Proxy A is my local proxy
and Proxy B is the the remote one. My local proxy has an ldap
authentication and is working. My remote proxy also has its own ldap
authentication feature. When I started to chain my remote proxy to my
local proxy however, remote users connected to the remote proxy is now
getting an error of "proxy authentication failure" even though they have
entered the right login and passwd. I rechecked even the cache_peer on
squid.conf on both proxies and here's what:
  
remote proxy:
cache_peer daffy.apme-ops.dhl.com parent 3128 3130
..........
authenticate_program /usr/local/squid/bin/squid_ldap_auth
ldap.hkg-hub.dhl.com
 
local proxy
authenticate_program /usr/local/squid/bin/squid_ldap_auth
ldap.apme-ops.dhl.com

What could be wrong? Any other thing I missed?
Joel
