LOGIN_PASSWD(8)		OpenBSD System Manager's Manual	       LOGIN_PASSWD(8)

NAME
     login_passwd - provide standard password authentication type

SYNOPSIS
     login_passwd [-s service] [-v wheel=yes|no] [-v lastchance=yes|no] user
		  [class]

DESCRIPTION
     The login_passwd utility is called by login(1), su(1), ftpd(8), and
     others to authenticate the user with passwd-style authentication.

     The user argument is the login name of the user to be authenticated.

     The service argument specifies which protocol to use with the invoking
     program.  The allowed protocols are login, challenge, and response.  (The
     challenge protocol is silently ignored but will report success as passwd-
     style authentication is not challenge-response based).

     If the wheel argument is specified and is not set to ``yes'', then the
     user will be rejected as not being in group ``wheel''.  This is used by
     su(1).

     If the lastchance argument is specified and is equal to ``yes'', then if
     the user's password has expired, and it has not been expired longer than
     ``password-dead'' seconds (see login.conf(5)), the user will be able to
     log in one last time to change the password.

     login_passwd will prompt the user for a password and report back to the
     invoking program whether or not the authentication was successful.
