[Samba] Re-doing tdbsam

[Karl Zander]

Running Samba 3.x with tdbsam.  Its a small nework of 4 
Windwos XP machines.  Having a little trouble adding the 
machines to the domain.  pdbedit shows duplication 
machines names and such.  Since its such a small number of 
machines, want to just start over with a fresh tdbsam as 
it seems faster then trying to clean it up.  Can we just 
delete the existing tdbsam?  Stop and restart Samba and 
have a clean tdbsam to work with?  Anything else to clean 
up?
