In this video I show you how to create a user and allow it to login to a openstack instance.
Add a user:
$ sudo adduser chris
Add user to sudoers group
$ sudo adduser chris sudo
Edit you sshd config file:
$ sudo nano /etc/ssh/sshd_config
Change Password Authentication from no to yes:
Restart ssh to pickup changes:
$ sudo restart ssh
Now you can login with your user and password with out a ssh key pair setup.
