Title:
  federated user creation creates duplicates of existing user accounts

Status in OpenStack Identity (keystone):
  New
Status in keystone package in Ubuntu:
  New

Bug description:
  Keystone 15.0.0-0ubuntu1~cloud0
  DISTRIB_CODENAME=bionic
  Charm cs:keystone-306 keystone-saml-mellon-3

  We had a situation where two user accounts were found with the same
  name and user ID in both the local_user and federated_user table.
  This meant that running `openstack user show --domain mydomain
  username2` would fail with "More than one user exists with the name
  'username2'".  Listing users would show only one user account, and
  using the user uuid to 'user show' was working fine.

  I ended up removing the two rows from local_user to work around this.

  The bug however, is that federated users with the same name as one
  that was already located in local_user shouldn't be created like that.

  mysql> select * from local_user;
