Suppose an organization that started out with Built-in users now wants to implement Single Sign-on (Enterprise) logins. The naming convention for their Lightweight Directory Access Protocol (LDAP) with the ArcGIS Online shortname may default to the same usernames that the built-in users had. When a new user sets up their Enterprise account in ArcGIS Online, it requires them to create a new username because the old one is taken.
To resolve this issue:
Note: If the person with the username that is to be deleted does not remember which email was used to create the account, simply go through the Forgot username? link in the Sign In page to have Esri send the email to all associated accounts; it specifies which one is Public.
