Samba PDC#1 - Configure Domain Controler2011/03/12

  Build Primary Domain Controller with Samba + OpenLDAP. LDAP Server is required to be running on your LAN and also the server you'd like to build as a PDC need to be a LDAP Client.

[1] Chane OpenLDAP server's settings.

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
Looking for configuration files...
