[Samba] Is DNS Scavenging working?

[Christian Naumer]

Hi Carlos,
we also have enabled this. However, I think there is a Bug where 
sometimes Samba creates the DNS Entry as static sometimes as dynamic. 
The static ones are never scavenged.

See this Bug (https://bugzilla.samba.org/show_bug.cgi?id=12451).



Regards


Christian
