invalid key specified when using SSH keys

[MaxiReglisse]

Hello everyone,

The execution of my playbook fails when users have SSH key(s). This is the error message (sorry for the layout, but github seems to have degraded the possibilities to write clean code...).

"msg": "invalid key specified: ['ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDNtoEXORkQPe92V60dfz5YdkKG/eXmK/kaCboh06UuGwCDhEZxXCRFtXTfleUlD2fygXrkr+w9KWWbp82XufDWZOxXCnfyJhxjstdMIljkBqg9ZxQY+D+N+bV7OhdFEGqycqX6y8/tKySf2x+i79gIq4V/mrnc8ME9iX/WMZA1Doscvhhbob0OWl3WLEjMDe1WENUbbHB23mQOI4ZF5GWV7JBX+HPYX6Gi1vWNUtw1WfEk2fAesIMbsDIemETWWZLiO+fL95TKybn7izakQobZX23Kem+7gK5iJqKIt9sDpWKcgymTL0RIE2WyAoVL7ShUVY2dkQiY9WUcGXJDAHQT matt@mshe']

However, this key is perfectly valid, as shown by the ssh-keygen -l command below.

root@pbs14200:~ # cat id_rsa_matt.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDNtoEXORkQPe92V60dfz5YdkKG/eXmK/kaCboh06UuGwCDhEZxXCRFtXTfleUlD2fygXrkr+w9KWWbp82XufDWZOxXCnfyJhxjstdMIljkBqg9ZxQY+D+N+bV7OhdFEGqycqX6y8/tKySf2x+i79gIq4V/mrnc8ME9iX/WMZA1Doscvhhbob0OWl3WLEjMDe1WENUbbHB23mQOI4ZF5GWV7JBX+HPYX6Gi1vWNUtw1WfEk2fAesIMbsDIemETWWZLiO+fL95TKybn7izakQobZX23Kem+7gK5iJqKIt9sDpWKcgymTL0RIE2WyAoVL7ShUVY2dkQiY9WUcGXJDAHQT matt@mshe

I wrote the following role to create users.

- name: Include variables from sudoers.yml
  include_vars:
    file: "{{ role_path }}/defaults/sudoers.yml"

- name: Create accounts in a loop on the user dictionary
  include_role:
    name: ryandaniels.create_users
  vars:
    comment:           "{{ user_item.comment }}"
    password:          "{{ user_item.password }}"
    primarygroup:      "{{ user_item.primarygroup }}"
    ssh_key:           "{{ user_item.ssh_key }}"
    exclusive_ssh_key: "{{ user_item.exclusive_ssh_key | default(yes) }}"
    user_state:        "{{ user_item.user_state }}"
    update_password:   "{{ user_item.update_password   | default(on_create) }}"
    username:          "{{ user_item.username }}"
    use_sudo:          "{{ user_item.use_sudo }}"
    use_sudo_nopass:   "{{ user_item.use_sudo_nopass }}"
  with_items: "{{ users }}"
  loop_control:
    loop_var: user_item

the data has been organized in accordance with the documentation and the previous role, in the users dictionary.

users:
  - username: matt
    user_state: present
    comment: Mattieu Latroy
    primarygroup: matt
    password: "$6$...EhO."
    cron_allow: yes
    use_sudo: yes
    use_sudo_nopass: yes
    servers:
      - linux

    exclusive_ssh_key: yes

    ssh_key:
      - "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDNtoEXORkQPe92V60dfz5YdkKG/eXmK/kaCboh06UuGwCDhEZxXCRFtXTfleUlD2fygXrkr+w9KWWbp82XufDWZOxXCnfyJhxjstdMIljkBqg9ZxQY+D+N+bV7OhdFEGqycqX6y8/tKySf2x+i79gIq4V/mrnc8ME9iX/WMZA1Doscvhhbob0OWl3WLEjMDe1WENUbbHB23mQOI4ZF5GWV7JBX+HPYX6Gi1vWNUtw1WfEk2fAesIMbsDIemETWWZLiO+fL95TKybn7izakQobZX23Kem+7gK5iJqKIt9sDpWKcgymTL0RIE2WyAoVL7ShUVY2dkQiY9WUcGXJDAHQT matt@mshe"

The debug mode shows that the data is correctly managed by the role:

        {
            "comment": "Mattieu Latroy",
            "cron_allow": true,
            "exclusive_ssh_key": true,
            "password": "$6$...EhO.",
            "primarygroup": "matt",
            "servers": [
                "linux"
            ],
            "ssh_key": [
                "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDNtoEXORkQPe92V60dfz5YdkKG/eXmK/kaCboh06UuGwCDhEZxXCRFtXTfleUlD2fygXrkr+w9KWWbp82XufDWZOxXCnfyJhxjstdMIljkBqg9ZxQY+D+N+bV7OhdFEGqycqX6y8/tKySf2x+i79gIq4V/mrnc8ME9iX/WMZA1Doscvhhbob0OWl3WLEjMDe1WENUbbHB23mQOI4ZF5GWV7JBX+HPYX6Gi1vWNUtw1WfEk2fAesIMbsDIemETWWZLiO+fL95TKybn7izakQobZX23Kem+7gK5iJqKIt9sDpWKcgymTL0RIE2WyAoVL7ShUVY2dkQiY9WUcGXJDAHQT matt@mshe"
            ],
            "use_sudo": true,
            "use_sudo_nopass": true,
            "user_state": "present",
            "username": "matt"
        },

I don't know what the problem is and I'd like to know if I've forgotten something or if there's a bug somewhere.

Thanks in advance for your feedback.

Ernest.
