adding a Samba Share for all users

Question:

I'd like to add a section in my smb.conf file (I know I have to edit the templates and all) to allow my users to be able to connect via smb using a Linux Terminal from K12LTSP. I'd like for them to be able to type in smb://servername/sharename

Example: smb://snoopy/home_directories

And then they'd be able to log in and select their own folder....or if I could get them right to their home folder that'd be nice. What I plan to do is to put a URL link using the smb:// format on their desktops....any ideas?

If I were to do something like this....how can I put all my users in there (I have about 600) without adding them one by one....can I do valid groups and use "everyone"? Is there a better way?

[home_directories]
comment = home_directories
path = /home
valid users = admin root dtrask
admin users = admin root me
write list = admin root me
public = no
writable = yes

thanks for any help you can give me
