Comment 10 for bug 24184

And more importantly, this spec would hash the passwords by pam as users were created initially so that every _new_ install would have working samba users, as well as upgraded users who had changed their passwords. I'll clarify this on the spec.

So, if you buy a new machine, do a fresh install of Feisty, and then install samba, you will be able to log in immediately to samba because your password was hashed in the format samba needs when you first set your password, even though samba wasn't installed. The hash is there waiting for samba when/if samba is installed.
