How can I stop samba from authenticating the guest? Currently, my user authenticates with PAM (ldap from Active Directory) and that is successful. But the user doesn't have any Unix account information -- so Samba falls back to the "guest" account. This is okay. Bu then Samba tries to authenticate again (via PAM) for this guest. And that fails: passdb/pampass.c:smb_pam_auth(510) smb_pam_auth: PAM: Athentication Error for user nobody passdb/pampass.c:smb_pam_error_handler(71) smb_pam_error_handler: PAM: Authentication Failure : Authentication failure I have tried this with guest account as nobody and as another valid Unix account. How can I get Samba to not try to authenticate again? I used "guest ok = yes" because the documentation says: "no password is required to connect to the service." But I do want the first PAM authentication to be required. (I just don't want the second to be done.) This is what I want: - must authenticate original, non-guest user via PAM; - then use one guest account but don't authenticate again. I tried "security = share" but that tries to do the authentication for the guest account first and fails. But if I don't use that "security = share" then I need to use "map to guest", but that doesn't apply -- because I don't want to use guest on bad passowrd or bad user. I want to use guest every time but only if the username provided authenticates first. Note: if I log in using a user that has a local account, it works fine. But I don't want to have every user setup locally too. I just want to use one guest account for all remote users that authenticate correctly via PAM. Any ideas? (This is Samba 2.2.3a-6 for Debian.)
