Overview

The ftpusers service module for PAM, pam_ftpusers provides functionality for only one PAM category: account management. In terms of the module-type parameter, this is the “account” feature.

Ftpusers Account Management Module

The ftpusers account management component (pam_sm_acct_mgmt()), succeeds if and only if the user is listed in /etc/ftpusers.

The following options may be passed to the authentication module:

debug

syslog(3) debugging information at LOG_DEBUG level.

no_warn

suppress warning messages to the user. These messages include reasons why the user's authentication attempt was declined.

disallow

reverse the semantics; pam_ftpusers will succeed if and only if the user is not listed in /etc/ftpusers.
