Debian used to install the winbind package when you installed the
'samba' package, you now need to install it separately.

You are confusing setting up 'winbindd' with installing the winbind

Debian needs to deal with its bug, it also needs to update that
message, samba no longer starts its internal winbind (I think it has
been removed), it starts the separate 'winbindd' deamon, this is why
you need the winbind package.

The Samba wiki is mainly written around using a self compiled Samba and
not on a package install, but you have made a few valid points, so I
will look into updating the wiki.
