samba - Mar 2015 - [3.6.6] Possible to allow password-free read/write access?

Hello

	At home, I use my Windows client host without entering a password,
and would like to access a local Linux host likewise, ie. without
being prompted for login/password while still having read/write
access.

Is this possible?

Currently, I created no Unix/Samba accounts for the Windows user, and
the following smb.conf only works in read-only mode (ie. I get an
error when trying to write):

================[global] 
workgroup = WORKGROUP
netbios name = LINUX

;a bit of security
hosts allow = 127.0.0.1 192.168.0.0/24
hosts deny = 0.0.0.0/0

;So users don't get 'System error 5 has occurred. Access is
denied."
when running "net view \\linux"
security = user 
map to guest = Bad User

[myshare] 
comment = Data
path = /myshare
writable = yes
guest ok = Yes

;DOESN'T WORK: WHICH USER TO USE?
;chown -R www-data /myshare
valid users = www-data

force create mode = 0644
create mask = 0664
security mask = 0664
force security mode = 0664
================
Thank you.

Yes indeed: Just run this:

=======chown -R nobody /myshare
=======
By default, "Bad User" matches to Unix user "nobody".

per smb.conf, you might want to try changing to "security = share" 
(assuming you don't have any shares that might require more restriction.


Did you try setting the linux directory permissions as 777-   at least 
for testing?

I read that "security = share" was deprecated in favor of
"security user", so that's what I used.

Turns out I had to run "chown nobody" on the share, since this is the
Unix user account Samba relies on by default when using "map to guest
= Bad User".

I'll read some more about how Samba handles user authentication +
authorization.

Thanks.
