There must be a better way of doing this, dfs shares ??

I would go to Ubuntu 18.04, this will get you a Samba supported
version, both 4.3.x & 4.4.x are EOL as far as Samba is concerned.
If you do go with 18.04, you will need to make some changes to the 'ad
backend lines, use these instead:

# 'ad' backend
# If uidNumber & gidNumber attributes in AD
# They must be inside 5000-1999999
#idmap config XXXXX:backend = ad
#idmap config XXXXX:range = 5000-1999999
#idmap config XXXXX:schema_mode = rfc2307
#idmap config XXXXX:unix_nss_info = yes
# If you want to use another group for the
# users primary group instead of Domain Users
# uncomment the next line as well
#idmap config XXXXX:unix_primary_group = yes

And yes you do need the lines, winbind will not work without them, you
just need the right lines depending on the backend type and if 'ad',
the right lines for the Samba version.

Well yes, but probably because you had 'path' in the [homes] share,
which is not normally used.
