Use civicrm profile to simultaneously create civi contact and drupal user
If from the profiles page (/civicrm/admin/uf/group?reset=1) I click more > Use - Create Mode, it redirects to a screen that does not have the Drupal fields (username/password), and can successfully create a CiviCRM contact. But this is weird and happens even with setting "Account creation required" selected. I would expect this page to show and reflect the Drupal fields as well with that setting selected.
When visiting the same url (https://www.mysite.com/civicrm/profile/create?gid=14&reset=1) as an anonymous user, I correctly see the Drupal account fields AND the CiviCRM fields, but upon hitting save am shown an error:
Profile Error Your profile is not saved and Account is not created.
Neither a Drupal account or CiviCRM contact are created. There are also no new log messages at /admin/reports/dblog to indicate why it didn't work.
