title: After user registered in wordpress the user should be inactive
body: <p>In registration, after user registered, they should confirm the email validation link, until they validate the email their role should be inactive and they should not able to login in to the website.</p>
  
  <p>Am adding the user using wp_insert_user(), in this function there is a field name call 'role' but I don't know what should be given there. I tried "inactive" but not working. Kindly suggest me.</p>
