Hello,

is this also true for master: (auth-zone clause) and/or stub-addr: 
(stub-zone clause)?

I mean, is there any way to define the prefered master in case of 
auth-zone clause, and define a second master as fallback in case there 
was no answer within a defined timeout?

If someone has already tried out/ knows the code I'd highly appreciate 
any hints.

Thanks,
