[mathias dufresne]

Hi all,

Using help of configure script we can found taht:

  --with-dnsupdate
            Build with dnsupdate support (default=yes)

what does taht really enable/disable?

A - Is this option related to DC only?
A1 - Is this to allow internal DNS to support DNS updates?
A2- Is this to allow all DNS sub-system to support DNS updates?
B - Is this for Samba as AD client?
