1 The pam_pwauth_suid authentication module uses a setuid program
2 to verify a password against the encrypted password in the
3 database used by the system. This way, an unprivileged user can
4 verify his own passsword stored in a shadow password database.
5 There might be some risk that the communication between the
6 invoking program and the setuid program is logged, or for abuse
7 for dictionary attacks.
