Samba BDC
2010/08/17
  Configure Samba BDC (backup domain controller). Of course, Samba PDC needs to be running in your LAN and also this Samba BDC is LDAP client.

[1] smb.conf is almost the same with PDC. Different section is 'domain master' section and LDAP server's IP address.

smbldap-tools script configuration

-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Before starting, check
. if your samba controller is up and running.
. if the domain SID is defined (you can get it with the 'net getlocalsid')

. you can leave the configuration using the Crtl-c key combination
. empty value can be set with the "." character
