[Samba] dbcheck reporting errors

[samba list]

Hi all,

Our domain is running perfectly, but for the fun of it, I tried a 
samba-tool dbcheck, and (unexpected actually!) it returned many errors, 
on many users, like this:

> ERROR: wrongly formatted userParameters on CN=username1,CN=Users,DC=samba,DC=company,DC=com, should not be psudo-UTF8 encoded
> Not changing userParameters from UTF8 encoding on CN=username1,CN=Users,DC=samba,DC=company,DC=com
(yes: it says "psudo-UTF8")

This is Version 4.2.5-SerNet-Debian-8.wheezy (upgraded from 4.1.17) in 
an AD config. We mostly use ADUC to manage users.

Are we having problems, without feeling it (yet)..?
