[Samba] Password-less Share on a Samba DC

[Tiago Dias]

Hello

I am setting up a samba 4 DC in my home server, and I have multiple 
shares I want to only be accessed after username/password input, and 
those are working fine. However, I also want to have one share that can 
be accessed by anyone in the network, without entering any credentials.
I searched around the internet and found that I could use "security = 
user" and "map to guest = Bad User", but when I try to access the share 
from a Windows client I still get the credentials popup, and can only 
see the share by either entering a real username and password or "\" in 
the username field and leaving the password blank.

Is there any way to have the share working the way I want it?

Thank you in advance.
