Re-login doesn't really work after changing password of API user

[iprok]

SUMMARY

When I change password for admin user using ansible task all following tasks fails. E.g. this playbook:

    - name: Configure zabbix server
      vars:
        ansible_network_os: community.zabbix.zabbix
        ansible_connection: httpapi
        ansible_httpapi_port: 80
        ansible_httpapi_use_ssl: false
        ansible_zabbix_url_path: ""
        ansible_host: zabbix80deb11

        ansible_user: Admin
        ansible_httpapi_pass: "verysecretpass"

      block:
        - name: Change password for default Admin
          community.zabbix.zabbix_user:
            username: Admin
            override_passwd: true
            current_passwd: "zabbix"
            passwd: "verysecretpass"
            usrgrps:
              - Zabbix administrators
              - Internal
          ignore_errors: true
          vars:
            ansible_httpapi_pass: "zabbix"

        - name: Get Admin user info using the NEW password
          community.zabbix.zabbix_user_info:
            username: Admin
          register: admin_info
          vars:
            ansible_httpapi_pass: "verysecretpass"

ACTUAL RESULTS

Provided playbook fails with such output (I turned on all debug logs):

I tried to print contents of self.connection._auth and got only {'Content-Type': 'application/json-rpc'}, and the json with the server response is {'jsonrpc': '2.0', 'error': {'code': -32602, 'message': 'Invalid params.', 'data': 'Session terminated, re-login, please.'}, 'id': '397...a0c2'}

I got a similar issue. I can get the Admin account password updated for Ansible, but fails to log in via web. API is fine. I have a similar command to create a new account and that works... just not the Admin account

This might help your issue if its what I am thinking...

The general flow is

1. generate password
2. then change the password
3. then update the Ansible var for the admin password to use the new password.
4. profit?
5. All remaining API calls use the new password and work correctly

VARS used

• zabbix_admin_b_password <-- the new password
• zabbix_port <-- the port Zabbix is running on
• zabbix_server <-- the servername / fqdn for Zabbix
• zabbix_admin_username <-- the username, set to 'Admin'
• zabbix_admin_password <-- the password for the username above, starts off as 'zabbix'
• zabbix_path <-- the path Zabbix is running on for the URL, set to '/'
• zabbix_tech_timezone <-- the timezone i want to use
• zabbix_tech_email <-- the email address to send notifications. email is disabled
