Hi everyone,

I'm back working on Samba subjects and rather than writing stupidities, I
decided to come and use your knowledge : )

nmbd: in modern configurations running nmbd is not necessary and could
perhaps even be seen as security issue: it seems to allow NetBIOS
authentication which is not secure.
Is that true or not?

winbindd: is responsible to grab information from AD to produce system
users (through NSS) and possibly provides a way for these generated system
users to authenticate against AD (through PAM)
Is that true or not?

smbd: the file server, at least for modern usage. It can also grab user
information from AD but not for system users, only for Samba users (the
applicative users, used to authenticate when accessing Samba and later, to
shares)
Is that true or not?

smb.conf -> username map: when adding "root = administrator" in the
file
referenced by "username map", the Samba user named administrator will
be
granted access to files that root system user can access. If some system
user is named administrator too, remote/Samba user named administrator will
not have access to files owned by system's administrator user.
Is that true or not?

Hoping you're all doing well, cheers,
