I'm still having this problem and hope that someone might be able to point
me in the right direction, below I have included more details:

using squid_ldap_auth from command line to query 2003 DC:

$ sudo /usr/local/squid/libexec/squid_ldap_auth -b "dc=mydomain,dc=net" -h
192.168.x.y -p 389 -D
"cn=Squid,ou=IT,ou=Users,ou=site1,ou=subcompany,dc=mydomain,dc=net" -w
password -f "sAMAccountName=%s" -d
user.name password
user filter 'sAMAccountName=user.name', searchbase 'dc=mydomain,dc=net'
squid_ldap_auth: WARNING, LDAP search error 'Operations error'
ERR Success
^C
$ sudo /usr/local/squid/libexec/squid_ldap_auth -b
"ou=subcompany,dc=mydomain,dc=net" -h 192.168.x.y -p 389 -D
"cn=Squid,ou=IT,ou=Users,ou=site,ou=subcompany,dc=mydomain,dc=net" -w
password -f "sAMAccountName=%s" -d
user.name password
user filter 'sAMAccountName=user.name', searchbase
'subcompany,dc=mydomain,dc=net'
attempting to authenticate user
'CN=user.name,OU=SystemAdmins,OU=IT,OU=Users,OU=site1,OU=subcompany,DC=mydomain,DC=net'
OK
^C
$
You can see above that I get "ERR Success" if I use the base of the domain
for the base dn but it works fine if I specify an OU. If I do these
queries on a Windows 2000 DC both are successful. I have tested
squid_ldap_group and it behaves exactly the same. Any help is greatly
appreciated.

Thnaks,
Colin

Yes, I can in some cases. If I am querying windows 2003 DC and the base DN
is the base of the domain ("dn=domain,dn=lan") then I get the following:

squid_ldap_auth: WARNING, LDAP search error 'Operations error'
ERR Success

But if I specify an ou ("ou=site1,dn=domain,dn=lan") then it works
correctly. If I query a Windows 2000 DC the it works either way.

Hi Colin, I had a tough time with getting the syntax, can you do command
line lookups using squid_ldap_auth ?
