I don't believe I have an issue with Time Machine functionality itself, only that Samba can't find my Time Machine directory because it is (unexpectedly) looking for the wrong path on the server so my Mac can't connect to the share. The same %U issue affects my standard [homes] share as well, so I don't think we have the same problem.

You cannot use 'winbind use default domain = yes' with multiple DOMAINS.

You have:

idmap config SERVER : backend = tdb
idmap config SERVER : range = 60000-69999

(Incidentally, the 'tdb' would probably be better off being 'rid')

and

idmap config DOMAIN : backend = rid
idmap config DOMAIN : range = 1106000000-1106200000

Either remove the 'SERVER' lines and use 'winbind use default domain = 
yes', or remove 'winbind use default domain = yes' and use usernames in 
the format 'DOMAIN\username'
