AFAIK no way to fix, only samba downgrade

How to downgrade Samba to 4.1.6 using apt-get
http://www.backupcentral.com/phpBB2/two-way-mirrors-of-external-mailing-lists-3/backuppc-21/issues-with-smb-shares-130329/#410878

I had to uninstall samba and smbclient together with backuppc first, then 
reinstall.

Is there any other way to fix this in samba 4.8.3 the downgrading to 4.1.7 ?
If not, then how to get samba 4.1.7 via apt.-get ?

Best regards
