36.10. Using Ansible to override the login name and home directory of an IdM user on a specific host

Procedure

1. Create your Ansible playbook file add-idoverrideuser-with-name-and-homedir.yml with the following content:

   ---
   - name: Playbook to manage idoverrideuser
     hosts: ipaserver
     become: false
     gather_facts: false
     vars_files:
     - /home/user_name/MyPlaybooks/secret.yml
   
     tasks:
     - name: Ensure idview_for_client1 is present
       idview:
         ipaadmin_password: "{{ ipaadmin_password }}"
         name: idview_for_client1
     - name: Ensure idview_for_client1 is applied to client1.idm.example.com
       idview:
         ipaadmin_password: "{{ ipaadmin_password }}"
         name: idview_for_client1
         host: client1.idm.example.com
         action: member
     - name: Ensure idm_user is present in idview_for_client1 with homedir /home/user_1234 and name user_1234
       ipaidoverrideuser:
         ipaadmin_password: "{{ ipaadmin_password }}"
         idview: idview_for_client1
         anchor: idm_user
         name: user_1234
         homedir: /home/user_1234

2. Run the playbook. Specify the playbook file, the file storing the password protecting the secret.yml file, and the inventory file::

   $ ansible-playbook --vault-password-file=password_file -v -i <path_to_inventory_directory>/inventory <path_to_playbooks_directory>/add-idoverrideuser-with-name-and-homedir.yml

3. Optional: If you have root credentials, you can apply the new configuration to the IdM client system immediately:

   1. SSH to the client system as root:

      $ ssh root@client1
      Password:

   2. On the IdM client, clear the SSSD cache:

      # sss_cache -E

   3. On the IdM client, restart the SSSD daemon:

      # systemctl restart sssd

Verification

1. SSH to IdM client as idm_user:

   # ssh idm_user@client1.idm.example.com
   Password:
   
   Last login: Sun Jun 21 22:34:25 2020 from 192.168.122.229
   [user_1234@client1 ~]$

2. Print the working directory:

   $ pwd
   /home/user_1234/
