Hi all, Our environment is 3 x AD DCs running Samba 4.0.19. I'm trying to present a public share from one of these, but the client always asks for username/password when I try to connect. I've got "guest account = nobody" and "map to guest = Bad User" in the [global] settings, and "guest ok = Yes" in the [sharename] settings, as per most of the guides I've seen online. According to testparm, "security = USER" is set by default as well, but I've also tried setting it manually, to no avail. Is there a special trick to make public shares work on Samba 4 AD DCs, or is it just not possible because of the domain permission model? Any suggestions would be much appreciated. Thanks, Rob
