[Samba] Change in behaviour for the "%U" substitution in 4.10.8?

[gac]

I opted for 'remove the SERVER lines' (since I don't remember why they are in there) - but this hasn't changed the behaviour. The log file contains a different error message, but still refers to the incorrect path

Thanks

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.
