As far as I know (tried it myself :) ), dbcheck won't fix it. I had the 
same issue in samba 4.5. The way I dealt with it, was when updating to 
4.7.x. I added new temporary DC with 4.7.x, allowed it to replicate all 
data (no uppercase errors in this DC), then for all DC's i one by one: 
demoted DC, removed samba (complete wipe), and installed fresh 4.7 and 
re-joined it as DC (same hostname and IP). Of course I had to be careful 
with FSMO roles, that is I had to move them between reinstalls.

In the end all my DC's were updated and database without this ou/OU or 
cn/CN error.

Of course You can do this without actual samba update, you just have to 
install "fresh" samba with version not affected by this error and join 
as DC, then recreate all DC's.

Maybe there is less "invasive" method, but I didn't know about it, and 
anyway I wanted to update DC's, so wasn't an issue for me. And now 
ldapcmp shows everything in order.
