I will set up two parallel pdns setups to test this. One using bind
as the recursor and the 2nd using the pdns recursor. The problem that
we were observing was a problem authenticating against the Active
Directory server. As far as my initial investigation went, the actual
SRV records were correctly returned by pdns+recursor and pdns+bind
but using bind as the recursor presented the additional records.
Assuming that the Active Directory DNS results are what it expects
here is the corresponding dig against one of the AD DNS servers. It
appears that it is only including the A records for the entries in
the SRV records:

I will try to do some more comparisons to see if in fact that is
