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