AWS systems allow by default access with a certificate only. This is a security measure.
Administrators who decide to lower the security standards by allowing ssh access through user/password credentials on SUSE SLES have to execute the following commands:
- Edit the /etc/ssh/sshd_config file.
- Change the entry "PasswordAuthentication no" to "PasswordAuthentication yes"
- Save the changes
- Restart the sshd daemon with the command
- $ service sshd restart
