- name: Create Active User

   user:

     name: "{{ item }}"

     uid: "{{ management_active_users[item].uid | default(omit) }}"

     comment: "{{ management_active_users[item].full_name | default('') }}"

     createhome: "{{ management_active_users[item].createhome | default('yes') }}"

     group: "{{ management_active_users[item].group | default(omit) }}"

     groups: "{{ management_active_users[item].groups | default('') | join(',') }}"

     shell: "{{ management_active_users[item].shell | default('/bin/bash') }}"

     append: "{{ management_active_users[item].append | default('no') }}"

     state: "{{ management_active_users[item].state | default('present') }}"

   with_items: "{{ management_active_users }}"

   when: management_active_users is defined

 - name: Setup Active User Password

   user:

     name: "{{ item }}"

     password: "{{ user_passwd | password_hash('sha512') }}"
     update_password: on_create

   with_items: "{{ management_active_users }}"

   when: management_active_users[item].password is defined

When  I set up update_password: on_create is not working, still will update the user password, how can i fixed it ?
