d_passwd(4)                      DG/UX 5.4.2                     d_passwd(4)


NAME
       dpasswd - log-in programs and passwords for dial-up devices

SYNOPSIS
       /etc/dpasswd

DESCRIPTION
       This file contains an entry for programs (such as shells) that
       login(1) can invoke for users logging into the system via dial-up
       devices.  Each entry includes the pathname of the shell program for
       which a dialup password is required and the encrypted password that
       the user must provide in order to invoke the program.  You have to
       create a dpasswd file yourself; the system does not create one for
       you.

       A dial-up device is any device that has an entry in the /etc/dialups
       file.  See dialups(4).  You have to create a dialups file yourself;
       the system does not create one for you.

       When a user logs into a dial-up device, login searches the d_passwd
       file to see if it contains an entry for the shell program specified
       in the user's passwd entry.  If such an entry is found, login
       requires that the user provide a second ("dial-up") password in
       addition to their personal password.  The program name in the user's
       passwd entry and the program name in the dpasswd file must match
       exactly.  E.g., /bin/csh and /usr/bin/csh will not be matched even
       though they reference the same file.

       The program /usr/bin/sh is treated as a special case.  If dpasswd
       contains an entry for /usr/bin/sh, the password for that entry will
       be used as the default dial-up password for all users whose passwd
       shell program doesn't match any of the other dpasswd entries.  In
       the case where no matching entry is found for a user and no
       /usr/bin/sh entry exists, the user is not prompted for a dial-up
       password.

       Here is a sample dpasswd entry:

       /bin/csh:xxxxxx:

       where xxxxxx is the encrypted password.
