i found the problem of those particular applications.
It is becasue there is installation faulty with slave
ldap where they are referring to. but my master is
fine, so i redirect them to master, everything runs
fine.
only the smbldap-tools still not working.
i have done what Quanah told me to, debug it. there
are some application in smbldap-tools communicate with
ldap(such as useradd), but the other doesn't. the ldap
bedug windows doensn't even move when i try to run
smblda-passwd command. maybe there is something wrong
with the applications.
