[Samba] Home directories and "guest ok" (was: Samba 2.2.3-1 package concerns)

Thank you very much for your timely response and your accurate assessment
of the situation with browsing home directories.

I'm sending a copy of this reply to the Samba mailing list since it looks
like my questions to follow don't have much to do with the Debian package
per se, anymore.

[Introduction to the Samba list: I found out quite by accident that if I
browsed //myserver/backup I got a list of files in /var/backups, which I
later found out thanks to Eloy is because Samba is browsing the home
directory of the user 'backup' which is /var/backups.]

According to the smb.conf(5) manpage "guest ok" is supposed to be defined
per service. I just checked my smb.conf and found that "guest ok = yes"
was only set in my netlogon, and printers services. Neither the "guest ok"
nor "public" directives appeared anywhere else.

I've already removed all "guest ok" directives for debugging purposes and
have found that one can still browse //myserver/backup (or the home
directories of other system accounts). Note, however, that at this point a
user -is- logged on. The server doesn't show anything to a computer where
a user has not properly logged on.

I also tried setting "guest ok = no" in the homes service, but browsing
the home directories of accounts like the 'backup' user is still possible.

This is not really that critical, since connections are made using the
user's account so one is still limited to his/her permissions. But it's
still not very nice. I wonder what's going on. Any ideas?

Thanks a lot in advance! :)
