[squid-users] Squid/ldap authentication via Novell NDS

Hi,
I am using Squid-2.5-STABLE7 as proxy on SLES 8 for users to
authenticate the browser access to the internet, the password
authentication works well until the Novell NDS changed to a new tree
structure which I have also changed accordingly in the squid.conf.

The old NDS tree that had worked well with squid LDAP settings are as
follow:
==============================================
Old NDS LDAP structure, cn=proxy,ou=access,ou=mckell,o=dpws

Squid.conf auth_param and external acl type;
auth_param basic program /usr/local/squid/libexec/squid_ldap_auth -b
o=dpws -f cn=%s pws-is2-nsrv

external_acl_type ldap_group concurrency=5 %LOGIN
/usr/local/squid/libexec/squid_ldap_group -s sub -b
ou=access,ou=mckell,o=dpws -f (&(cn=%g)(uniquemember=%u)) -B o=dpws -F
(cn=%s) pws-is2-nsrv

acl WEBGROUP external ldap_group Proxy

The NEW NDS's tree that failed to work with squid has the following
settings:
==============================================
New NDS LDAP structure, cn=proxy,ou=People,o=commid

Squid.conf auth_param and external acl type;
auth_param basic program /usr/local/squid/libexec/squid_ldap_auth -b
o=commid -f cn=%s EDIR1NW
external_acl_type ldap_group concurrency=5 %LOGIN
/usr/local/squid/libexec/squid_ldap_group -s sub -b ou=People,o=commid
-f (&(cn=%g)(uniquemember=%u)) -B o=commid -F (cn=%s) EDIR1NW
acl WEBGROUP external ldap_group Proxy

I used tcpdump to monitor LDAP packets between the client and the new
NDS server EDIR1NW and saw the ldap packets communicating. I can not see
any messages/erros why the authentication failed. I don't believe there
is anything wrong with the new NDS server because other Novell clients
work well with it.

Can someone please shed light on this problem.
Many thanks.
