-.Sh NAME
-.Nm pam_ftp
-.Nd FTP PAM module
-.Sh SYNOPSIS
-.Op Ar service-name
-.Ar module-type
-.Ar control-flag
-.Pa pam_ftp
-.Op Ar options
-.Sh DESCRIPTION
-The FTP authentication service module for PAM,
-.Nm
-provides functionality for only one PAM category:
-authentication.
-In terms of the
-.Ar module-type
-parameter, this is the
-.Dq Li auth
-feature.
-It also provides a null function for session management.
-.Ss FTP Authentication Module
-The FTP authentication component
-.Pq Fn pam_sm_authenticate ,
-authenticates the anonymous user
-(usually
-.Dq anonymous
-or
-.Dq ftp )
-usually by simply requesting an email address as a password.
-The supplied email address is broken up
-into its username and host parts,
-and these are assigned to the
-.Dv PAM_RUSER
-and
-.Dv PAM_RHOST
-facilities respectively.
-.Pp
-This module is intended for the
-.Xr ftpd 8
-service.
-.Pp
-The following options may be passed to the authentication module:
-.Bl -tag -width ".Cm no_warn"
-.It Cm debug
-.Xr syslog 3
-debugging information at
-.Dv LOG_DEBUG
-level.
-.It Cm no_warn
-suppress warning messages to the user.
-These messages include
-reasons why the user's
-authentication attempt was declined.
-.It Cm no_anon
-Disallow anonymous access.
-.It Cm ignore
-Ignore the password supplied,
-and do not use its constituent parts
-(username and hostname)
-as
-.Dv PAM_RUSER
-and
-.Dv PAM_RHOST
-respectively.
