Very interesting.  You can see why I don't normally suggest this tool.

You could either rename those system users back to English (for now) in
 the database, or to change the template see the files in setup/ in
your install tree. 

You would notice that skipping --full makes it less aggressive, but
perhaps not enough. 

Finally, you could use the new samba-tool domain schmeaupgrade in Samba
4.8 to try and upgrade the schema using the adprep ldif files (these
are on the web).

I hope this helps,
