[Samba] Winbindd where to use it ? in which environnement ?

[David Touzeau]

Dear

I need help about know what is the real necessary to use Winbindd
daemon ?

After reading many wikis it seems that you need to use Winbindd only
when you need to connect samba to any "Microsoft Windows NT domains"
such has NT4 PDC or Active Directory.

Is it true that you "did not need" winbindd when you want Samba act has
a Primary Domain Controller ?

Best regards and thanks for your help.
