Share w/o ask a login

[Jair Valmor Basso Junior]

If I wanna make my users connect to a share or printer without providing a
log and password, how I do that?
I can create a account on the samba server for all my users, but I
dont wanna do that, I wanna give them access to the shares even if they
put the wrong password, or use a login who isnt in the /etc/passwd of the
samba server.

Some idea?

Thanks!
