Autenthication error after having created new user

If you delete a user and create a new one in Linux it can happen that you get this message when the new user is logged in:

Code: Select all

passwd: User not known to the underlying authentication module

It happened to me in Arch. :berserk2

So it seems like some old data were left on the box. The new user was auto logged in, but I always got that annoying warning. That is an indication that something is wrong +1 (even if everything works).

So to fix it, I simply re-installed pam (rather than looking for corrupted files in /etc/pam.d/).

Code: Select all

sudo pacman -S pam

PAM stands for Pluggable Authentication Modules and provides dynamic authentication support for applications and services in a Linux system.

That took care of it :smug
