### NAME

pam_ftpusers - ftpusers PAM module

### SYNOPSIS

[service-name] module-type control-flag ```pam_ftpusers` [options]

### DESCRIPTION

The ftpusers service module for PAM 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`.

### SEE ALSO

ftpusers(5), pam.conf(5), ftpd(8), pam(8)

### AUTHORS

The pam_ftpusers module and this manual page were developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (``CBOSS''), as part of the DARPA CHATS research program.

### BUGS

The current version of this module parses an older format of the ftpusers(5) file and should not be used. ftpd(8) will keep using its built-in ftpusers(5) parsing code until the parser code in the pam module is fixed.
