samba internal DNS, how to set TTL?

[David Mansfield]

Hi,

Is there a way to set the TTL of different kinds of records in the 
samba4 internal DNS?

The problem is that PTR records are getting a TTL of 0, so they cannot 
be cached at all.  This is creating quite a bit of DNS traffic.  The A 
records, however, get a TTL of 900, which seems reasonable.

I have looked at samba-tool options and can't find a way to set this.
