[Samba] Maybe working - Re: BIND DLZ zone transfers

[L.P.H. van Belle]

Hai, 


I have my setup like this. 

Samba4 DC1. (bind9_dlz)		=> proxy1 (bind9 slave) 
				      => proxy2 (bind9 slave)
Samba4 DC2. (bind9_dlz)		+ backup config with slave bind settings, 
					  if dc1 is down. (a scripted setup) 
Dc1-2	Synced through samba AD. 

Pc's querie proxy 1 and proxy2. 
After adding or chaning a record, its synced within 5 min, have had any problems with it. 


Greetz, 

Louis
