Re: [Samba] Internal DNS migrate to Bind9_DLZ




Hi Rowland,

I didn't build samba, I'm running the sernet packages,
# rpm -qa | grep sernet
sernet-samba-libsmbclient0-4.8.6-16.el7.x86_64
sernet-samba-ad-4.8.6-16.el7.x86_64
sernet-samba-libs-4.8.6-16.el7.x86_64
sernet-samba-client-4.8.6-16.el7.x86_64
sernet-samba-winbind-4.8.6-16.el7.x86_64
sernet-samba-common-4.8.6-16.el7.x86_64
sernet-samba-4.8.6-16.el7.x86_64

I don't mind having to remove and rebuild bind, but...
Excuse my ignorance, but what I don't understand is that I have a test DC
with random zones/data and migrating from INTERNAL DNS to BIND9 wasn't an
issue. The only difference between the two environments is that my test
site has 1 DC and my prod is 7 DC's.
My test environment is working 100% as is, same packages as prod.

Kind Regards
