The /etc/d_passwd File

Because most users will be running a shell when they log in, all shell programs should have entries in /etc/d_passwd. Such programs include uucico, sh, ksh, and csh. If some users run something else as their login shell, include that login shell in the file, too.

If the user's login program (as specified in /etc/passwd) is not found in /etc/d_passwd, or if the login shell field in /etc/passwd is null, the password entry for /usr/bin/sh is used.

• If the user's login shell in /etc/passwd matches an entry in /etc/d_passwd, the user must supply a dial-up password.

• If the user's login shell in /etc/passwd is not found in /etc/d_passwd, the user must supply the default password. The default password is the entry for /usr/bin/sh.

• If the login shell field in /etc/passwd is empty, the user must supply the default password (the entry for /usr/bin/sh).

• If /etc/d_passwd has no entry for /usr/bin/sh, then those users whose login shell field in /etc/passwd is empty or does not match any entry in /etc/d_passwd will not be prompted for a dial-up password.

• Dial-up logins are disabled if /etc/d_passwd has only the following entry: /usr/bin/sh:*:
