NAME

       pam_ftp - PAM module for anonymous access module

SYNOPSIS

       pam_ftp.so [debug] [ignore] [users=XXX,YYY,...]

DESCRIPTION

       pam_ftp is a PAM module which provides a pluggable anonymous ftp mode of access.

       This module intercepts the user's name and password. If the name is ftp or anonymous, the
       user's password is broken up at the @ delimiter into a PAM_RUSER and a PAM_RHOST part;
       these pam-items being set accordingly. The username (PAM_USER) is set to ftp. In this case
       the module succeeds. Alternatively, the module sets the PAM_AUTHTOK item with the entered
       password and fails.

       This module is not safe and easily spoofable.

OPTIONS

       debug
           Print debug information.

       ignore
           Pay no attention to the email address of the user (if supplied).

       ftp=XXX,YYY,...
           Instead of ftp or anonymous, provide anonymous login to the comma separated list of
           users: XXX,YYY,.... Should the applicant enter one of these usernames the returned
           username is set to the first in the list: XXX.

MODULE TYPES PROVIDED

       Only the auth module type is provided.

RETURN VALUES

       PAM_SUCCESS
           The authentication was successful.

       PAM_USER_UNKNOWN
           User not known.

EXAMPLES

       Add the following line to /etc/pam.d/ftpd to handle ftp style anonymous login:

           #
           # ftpd; add ftp-specifics. These lines enable anonymous ftp over
           #       standard UN*X access (the listfile entry blocks access to
           #       users listed in /etc/ftpusers)
           #
           auth    sufficient  pam_ftp.so
           auth    required    pam_unix.so use_first_pass
           auth    required    pam_listfile.so \
                      onerr=succeed item=user sense=deny file=/etc/ftpusers
