  access_key_ids:
    description:
      - A list of the keys that you want impacted by the access_key_state paramter.
  groups:
    description:
      - A list of groups the user should belong to. When update, will gracefully remove groups not listed.
    required: false
    default: null
  password:

  update_password:
    required: false
    default: always
    choices: ['always', 'on_create']
    description:
     - C(always) will update passwords if they differ.  C(on_create) will only set the password for newly created users.
notes:
  - 'Currently boto does not support the removal of Managed Policies, the module will error out if your user/group/role has managed policies when you try to do state=absent. They will need to be removed manually.'
