I've just set up a minimal install on my netbook (the default was too resource hungry, so I figured I'd customize the install and learn something about linux at the same time!)

No problems logging in as root, but when I create a new user and try to login as them I just get the "Login incorrect" error. I'm certain the password is correct, though the secure log displays an authentication error. Am I missing a permission somewhere?

useradd test
usermod -p [pwd] test

Shell is added automatically I think (checking password file says shell is /bin/bash) I've tried adding the user to the sudo-ers group usermod -a -G wheel which doesn't help. I've kept the password simple in order to rule out human error.

First: EDIT: original post edited to clarify, just a typo

Second: passwd is recommended before usermod -p (read man usermod) (if passwd is available on your system, of course, maybe it isn't (though I don't know a mainstream Linux where this isn't the case)).

Third: usermod -p does not take the cleartext password! Read man usermod. If you look in /etc/passwd, you'll see the password you entered with usermod -p in clear text, but when you try to log in it will be assumed that the password entry is encrypted.

Your assumption is correct. Thanks for the suggestions, I'll be able to try them later. – darkblackcorner Apr 4 '12 at 10:25
Wow, now I realise what a silly question that was, using "passwd" solved my problem. Thanks for your help! – darkblackcorner Apr 5 '12 at 7:37
