Hi Steve, getting the A record working should be easy, I think that the 
OP is trying to get sssd to update the ipaddress of the AD DC !

He initially posted (in the log extract):

  [resolv_gethostbyname_dns_query] (0x0100): Trying to resolve A record 
of 'ashanti' in DNS

He then posted:

nsupdate -g -D
setup_system()
reset_system()
user_interaction()
server 10.2.1.6


And a bit lower down:

this is my hosts file, ashanti is the AD

# 10.2.1.6      ashanti.tissisat.co.uk  ashanti

So, unless I am greatly mistaken, the OP is trying to update the record 
for the AD DC, something he shouldn't be doing, he needs to get dns info 
on the server set to a fixed ip with correct records in /etc/hosts and 
then try again from a CLIENT!
