Within smb. conf, which security setting will NOT require that a client connect using a valid usernarne and password before connecting to a shared resource?

`security = user` requires clients to authenticate with a valid username and password recognized by Samba.

When `security = share` is configured in `smb.conf`, Samba authenticates access at the share level, meaning clients do not need to provide a valid username and password to connect; access is determined by the permissions configured for the specific share.

`security = server` mandates that clients authenticate against another SMB server, which still requires valid credentials.

`security = guest` maps client connections to a guest account, but it is often used in conjunction with other security modes or share configurations; `security = share` is the explicit mode that directly permits connection without an authenticated user.
