Hi Andrew

I think that this thread is finally getting end users like me nearer the 
mark. Plain English answers are a must for folk like us.

When I type samba I seem to get smbd whether I like it or not. It works 
fine as a file server.
Is this what we call s3fs?
Is that different from the smbd I get with running smbd on s S3.6 box?

What does nmbd do? Does it get started when I call samba?

Does winbindd get started along with smbd when I call samba too? it 
seems to be because nsswitch with winbind (with the correct links) 
allows getent paswd/group to work.

As I say, simple, short yes/no answers would be most welcome.

Cheers,
Steve
