Problem is, Samba 4.10.8 works for me with '%U' ;-)

with these lines in smb.conf:

     idmap config SAMDOM : backend = ad
     idmap config SAMDOM : schema_mode = rfc2307
     idmap config SAMDOM : range = 10000-999999

     template homedir = /home/%U

    comment = Home Directories
    browseable = no
    read only = No
    create mask = 700
    directory mask = 700

I can log in to the computer and I can also connect via Samba to a users 

Yes, I know the above lines use the 'ad' backend, but I have no reason 
to think that 'rid' wouldn't also work.
