	Maybe, do you have your other parameters like
'security', 'invalid users', probably the result of
'testparm' and 'testparm -v' would make the trick. ;)

	The default configuration of samba (from official
samba source) is pretty sane, but security is a process
not a product, so you may have more higher standards of
security than others.

	'testparm' probably can answer that. ;)

	Long time ago, and 'old school' sysadmin said
to me that you should never trust the defaults, always
explicit add in the config file what you want, and if
the default change you will be safe.

	testparm can show you the values as they are
now, you can them make the result of testparm your new
smb.conf, but there is no big point on doing that if
you trust the default values.

	The Official Samba HOWTO has tips about security
all over the chapters, restrict the bind interfaces, the
IPs networks, the users, for example, some people use
'valid users = %S' in their [homes].

	Samba is simple, it just requires some patience,
care and attention. ;)   And so far, I didn't see any
"big security hole", but again, your security is as
strong as the weakest link in the chain.  The type of
your passwords, the measures to ensure they are safe
and with right permissions, and other small options can
make the difference.


> P.S. I AM reading all the howtos and Faqs and things!

	That's good. ;)

	Kind regards,
