The easiest way I've found, if you just want to verify their username & password, you can do this: $ds=ldap_connect("ldap://yourdc.yourdomain.com"); // Fix for Windows 2003 AD ldap_set_option($ds, LDAP_OPT_PROTOCOL_VERSION, 3); ldap_set_option($ds, LDAP_OPT_REFERRALS, 0); if ($ds) { $r=@ldap_bind($ds, $aduser, $adpass); $adauth = "No"; // prevent insertion // verify binding if ($r) { $adauth = "Yes"; } else { $adauth = "No"; } // end ad check } ldap_close($ds); If you need groups and such, good luck.
