[Samba] Can't join pc to domain with smbldap-tools but can with smbpasswd

[John H Terpstra]

I recommend that you follow chapter 5 of the book "Samba-3 by Example".
This fully documents every step in minuted detail to get your Samba/LDAP 
server operational. The last review (done Saturday) used smbldap-tools-0.9.1.

If you experience any problems please report them to me directly. Be sure to 
state the section number and step number that are causing you trouble.

I promise to fix anything that is causing trouble in the book. It is simply an 
impossible task to assist everyone on this list individually with their own 
custom configuration.
