[Samba] Acronyms: what is PDC and BDC?

[L.P.H. van Belle]

Forget PDC of BDC , ( not if you using samba 3, there it exists) 


samba 3, then we talk in PDC/BDC style ( think in master - slave ) 
samba 4, the we talk in AD-DC style ( think multi master ) ( and slave maybe bit as in RO ADDC ) 
and this is why we always must tell which samba we are working with..  ;-) 

>Yes, good. First; primary, hence PDC?  No, still AD-DC  
>AD doesn't have a PDC. half correct it has a PDC-emulator ;-) 

as the wiki says..

The "PDC emulator" master acts in place of the "Primary Domain Controller" 

=> !! if there are Windows NT 4.0 domain controllers (BDCs) remaining within the domain  !! <= 

correct me if i'm wrong.. 

greetz, 

Louis
