[David GUAN]

hi, i have installed daemontools-0.76+ucspi-tcp-0.88+qmail-1.03 with qmail-ldap-1.03-20011001a.patch in rh7.2, and my ldapserver is netscape directory server 3.0 runing in sun sparc machine, and basedn is o=lserver.k1390.com, ldapserver's superuser is ldapadm, password=abcd1234,   my questions are: 1. how to setup my ~control/ldapserver,ldapbasedn,ldaplogin,ldappassword? is that the four files enough? 2. how to setup the pop3 run_script? 3. can i user qmail-ldaplookup to test the connection to ldapserver?   Thank for help!!
