[Samba] Autoaccept all authentications to mitigate disabled guest logins in Windows 10 build 1709
Hello, guest logins are not allowed anymore in Windows 10 build 1709 by default. Due to company restrictions I am not allowed to reenable that in windows group controls. I now like to authorize all connections independent of the current user and password and just allow access so Windows thinks it has an authenticated connection and allows access. Is this somehow possible by using strange PAM configuration or by other dirty tricks without modifying the Samba source code? The server just provides readonly shares to everyone, so I don't care for any credentials anyway. Regards, Daniel Migowski

Hai, ... man smb.conf .... Have you tried that, that should work ;-) . There you should see something like this. [Global] map to guest = Bad Password [ashare] path = /home/public/share read only = yes guest ok = yes Look it up in the manual to see these settings explained, and dont forget to set the correct rights on the shared path.

Hai, Already tried the bad user option. Samba still answers the client that guest mode is to be used, but here is the problem. Windows 10 forbids guest mode now because of Security concerns! I need a way for Samba to accept the challenge response answer regardless of the user so Windows believes it was authenticated. Any hack no matter how dirty is greatly appreciated.

Any hack no matter how > dirty is greatly appreciated.The issue is that the server must respond with a security hash involving the password the user used. Hacks can't fake up knowing what the user set.
