Chapter 3. Using Ansible to manage IdM user vaults: storing and retrieving secrets
This chapter describes how to manage user vaults in Identity Management using the Ansible vault module. Specifically, it describes how a user can use Ansible playbooks to perform the following three consecutive actions:
The user can do the storing and the retrieving from two different IdM clients.
Prerequisites
- The Key Recovery Authority (KRA) Certificate System component has been installed on one or more of the servers in your IdM domain. For details, see Installing the Key Recovery Authority in IdM.
3.1. Ensuring the presence of a standard user vault in IdM using Ansible Copiar enlaceEnlace copiado en el portapapeles!
Follow this procedure to use an Ansible playbook to create a vault container with one or more private vaults to securely store sensitive information. In the example used in the procedure below, the idm_user user creates a vault of the standard type named my_vault. The standard vault type ensures that idm_user will not be required to authenticate when accessing the file. idm_user will be able to retrieve the file from any IdM client to which the user is logged in.
Prerequisites
You have configured your Ansible control node to meet the following requirements:
- You are using Ansible version 2.14 or later.
-
You have installed the
ansible-freeipapackage. - The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
-
The target node, that is the node on which the
ansible-freeipamodule is executed, is part of the IdM domain as an IdM client, server or replica. - You know the password of idm_user.
Procedure
Navigate to the MyPlaybooks directory:

Set the
ipaadmin_passwordvariable to the password of idm_user. -
Set the
uservariable to idm_user. -

3.2. Archiving a secret in a standard user vault in IdM using Ansible Copiar enlaceEnlace copiado en el portapapeles!
Follow this procedure to use an Ansible playbook to store sensitive information in a personal vault. In the example used, the idm_user user archives a file with sensitive information named password.txt in a vault named my_vault.
Prerequisites
You have configured your Ansible control node to meet the following requirements:
- You are using Ansible version 2.14 or later.
-
You have installed the
ansible-freeipapackage. - The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
-
The target node, that is the node on which the
ansible-freeipamodule is executed, is part of the IdM domain as an IdM client, server or replica. - You know the password of idm_user.
- idm_user is the owner, or at least a member user of my_vault.
- You have access to password.txt, the secret that you want to archive in my_vault.
Procedure

ipaadmin_principalvariable to idm_user. -
Set the
ipaadmin_passwordvariable to the password of idm_user. -

3.3. Retrieving a secret from a standard user vault in IdM using Ansible Copiar enlaceEnlace copiado en el portapapeles!
Follow this procedure to use an Ansible playbook to retrieve a secret from the user personal vault. In the example used in the procedure below, the idm_user user retrieves a file with sensitive data from a vault of the standard type named my_vault onto an IdM client named host01. idm_user does not have to authenticate when accessing the file. idm_user can use Ansible to retrieve the file from any IdM client on which Ansible is installed.
Prerequisites
You have configured your Ansible control node to meet the following requirements:
- You are using Ansible version 2.14 or later.
-
You have installed the
ansible-freeipapackage. - The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
-
The target node, that is the node on which the
ansible-freeipamodule is executed, is part of the IdM domain as an IdM client, server or replica. - You know the password of idm_user.
- idm_user is the owner of my_vault.
- idm_user has stored a secret in my_vault.
- Ansible can write into the directory on the IdM host into which you want to retrieve the secret.
- idm_user can read from the directory on the IdM host into which you want to retrieve the secret.
Procedure
Navigate to the MyPlaybooks directory:
cd ~/MyPlaybooks/
$ cd ~/MyPlaybooks/Copy to Clipboard Copied! Toggle word wrap Toggle overflow Make a copy of the /usr/share/doc/ansible-freeipa/playbooks/vault/data-archive-in-symmetric-vault.yml Ansible playbook file. For example:
cp /usr/share/doc/ansible-freeipa/playbooks/vault/retrive-data-symmetric-vault.yml retrieve-data-symmetric-vault-copy.yml
$ cp /usr/share/doc/ansible-freeipa/playbooks/vault/retrive-data-symmetric-vault.yml retrieve-data-symmetric-vault-copy.ymlCopy to Clipboard Copied! Toggle word wrap Toggle overflow Open your inventory file and mention, in a clearly defined section, the IdM client onto which you want to retrieve the secret. For example, to instruct Ansible to retrieve the secret onto host01.idm.example.com, enter:
[ipahost] host01.idm.example.com
[ipahost] host01.idm.example.comCopy to Clipboard Copied! Toggle word wrap Toggle overflow - Open the retrieve-data-standard-vault.yml-copy.yml file for editing.
-
Adapt the file by setting the
hostsvariable to ipahost. Adapt the file by setting the following variables in the
ipavaulttask section:-
Set the
ipaadmin_principalvariable to idm_user. -
Set the
ipaadmin_passwordvariable to the password of idm_user. -
Set the
uservariable to idm_user. -
Set the
namevariable to my_vault. -
Set the
outvariable to the full path of the file into which you want to export the secret. Set the
statevariable to retrieved.This the modified Ansible playbook file for the current example:

Verification
SSHto host01 as user01:ssh user01@host01.idm.example.com
$ ssh user01@host01.idm.example.comCopy to Clipboard Copied! Toggle word wrap Toggle overflow View the file specified by the
outvariable in the Ansible playbook file:vim /tmp/password_exported.txt
$ vim /tmp/password_exported.txtCopy to Clipboard Copied! Toggle word wrap Toggle overflow
You can now see the exported secret.
