Linuxcare: Dear Lina: Darkness Befalls

“Dear Lina,
There is something about my system that is bewildering me. I need
to fix it soon, because we have some new hires coming in about a
week, and it’s going to be hard giving them their accounts

When I create new users, they can’t login. I edit the
shadow file and add the hash for the default password, which has
worked many, many times before, so I just can’t figure out what’s
wrong now.

“I’m tearing my hair out. Hope you have an answer for me before
I go bald.”
