Centralisation of authentication of users, groups etc. You only need to
add users etc in one place and they are available everywhere in the domain.

If you join a samba machine to a domain it will look to the domain
server for authentication, samba will ignore any local users, so the
answer to your question is very probably 'No'. There may be some way of
making it work, but it will involve some contorted way of doing things
that I am not aware of and will probably be not recommended.
You originally seemed to be running a 'workgroup', this is a simple way
of sharing directories etc and the users need to be both Unix and samba
users, when you join a domain, all the users are just 'domain' users.
Once you have joined a domain, you can only go back if you stop samba,
remove all the samba databases, reset smb.conf and then restart samba,
you will then need to re-add all your local users to samba.
Why do you need to connect to the domain ? if this was known, there may
be another way round this.
