pam_ftp - PAM module for anonymous access module
pam_ftp.so [debug] [ignore] [users=XXX,YYY,...]
pam_ftp is a PAM module which provides a pluggable anonymous ftp mode
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.
Print debug information.
Pay no attention to the email address of the user (if supplied).
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.
