If you want to create a nologin user, you should specify that to the shell argument like this:

  - name: Add user "nagios"  
    user:
      name: nagios
      groups: nagios
      shell: /sbin/nologin
      create_home: no
      append: yes
      comment: "Nagios nologin User"
      state: present
    become: true
