Now I've got another samba server (pwdserver). All of my users are defined in
the /etc/passwd of the pwdserver. Below are from the related smb.conf files:

Original PDC:
password server=pwdserver
encrypt passwords=yes

encrypt passwords=no

However the original PDC does not accept the membership requests from an NT WS
4.0 client. I assume the smbpasswd will placed on the PDC but not the
pwdserver (since encryption is set to no on the pwdserver)
