Before I do anything stupid I wish to confirm that you did not accidentality
leave out the SVR RR type.  Given that the priority, weight, and port values
are specified it seems to me that the SRV type itself should also be present. 
Is this what you intended?

samba-tool dns delete 127.0.0.1 \
  _msdcs.brockley.harte-lyne.ca \
  _ldap._tcp.pdc \
  "SMB4-1.brockley.harte-lyne.ca SRV 389 0 100"

My mistake.  The reason that I was working on the DC in the first place was in
respect to time synchronization and I was dealing with ntp.  I just never
mentally switched gears from that context.

Thank you.

Well no and I do not know what happened, I arranged the command as I
thought you would need (from what you have posted) and cut & pasted it
into the post to the list, just like this:

samba-tool dns delete 127.0.0.1 _msdcs.brockley.harte-lyne.ca
_ldap._tcp.pdc SRV "SMB4-1.brockley.harte-lyne.ca 389 0 100"

Except somehow the 'SRV' went walk about.

No problem, it is very easy to get fixated on something.
