This is contrary to what the wiki says.
https://wiki.samba.org/index.php/Setup_a_Samba_AD_Member_Server
This page indicates that as long as the client can resolve names in the 
domain DNS zone (in my case ads.connon.me.uk) they should be fine.

I can confirm this isn't happening since I can resolve (for example) the 
SRV records on _ldap._tcp.ads.connon.me.uk through my forwarders, you 
can even test this yourself with `dig -t SRV 
_ldap._tcp.ads.connon.me.uk` or similar.

I'm currently looking into whether there are any records missing.

Regards,
Richard
