[Samba] Floating IP breaks AD replication

[Sven Wick]

Hi,

I have a setup with 2 DCs
which works just fine.

Since we have some legacy systems
which can't deal with 2 DNS Names
I used ctdb to manage a floating IP (in addition to the fixed IPs)
between the DCs which works great also.

But then the replication breaks
for some parts (Users still were replicated)
because the floating IP was added
to the internal DNS zone
and one of the DC tried to replicate
to itself after some failover tests.

Can I prevent somehow that the floating IP
gets added to the internal DNS zone
or what could be another approach?
