From 8d972df185de6e841a1752b67e466e8ffc95bfac Mon Sep 17 00:00:00 2001 From: James Knight Date: Sat, 23 May 2015 13:51:37 -0400 Subject: [PATCH] scripts/mkusers: allow users with no password value set The following allows a user definition to specify that a created user entry should not have a password value set. Original implementation allowed a user definition to provide a password value of "=" (no quotes) to generate a crypt-encoded empty string value. In some cases, it may be desired to have no value specified for a user's password. By using a value "-" for a password, no value will be set in the shadow value. An example when this can be used is when logging into a terminal. Logging into a session with an encoded empty password will prompt a user to enter a password since it does not know the password is empty. If the password field blank, a login session will not prompt for a password. Signed-off-by: James Knight Acked-by: "Yann E.
