Thanks to your input, I've been able to run the samba_upgradeprovision script.
But the full oprion fails with :
Creating a reference provision
WARNING: no network interfaces found
No IPv4 address will be assigned

Update base samdb by searching difference with reference one

Your system is as it was before the upgrade
This attribute comes from an extension for HP-UX (ldapux) which allows me to identify my HPUX users.
I also have other attributes coming from the deprecated MSFU3.5 but We don't use those attributes anymore.
Do you think the samba_upgradeprovision without --full option would be enough ? I don't really uderstand the difference between with and without this option.

The issue is that this script was never tested with non-ascii names.
Each instance of
"(distinguishedName=%s) % user_dn
in the script needs to be updated to be:
"(distinguishedName=%s)" % ldb.binary_encode(user_dn)
