I have a problem authenticating a squid server (on Debian Etch) against ldap on a Win2000 AD with IP address 10.0.0.10: In the AD I have - a domain: domain.com - a group Users - in that group I have a user Administrator with password aaa (and full access), and a user squid with password bbb. I try to authenticate the squid user: # /usr/lib/squid/ldap_auth -d -R -b "ou=Users,dc=domain,dc=com" -D "cn=Administrator,ou=Users,dc=domain,dc=com" -w "aaa" -h 10.0.0.10 I enter: squid bbb I get: attempting to authenticate user 'uid=squid,ou=Users,dc=domain,dc=com' ERR Success It should be an OK. I've been trying all kind of variations, no no success so I'm despite. Anyone who can help me? What am I doing wrong? Thank you. P.
