Overview
When creating Okta-mastered accounts, users may see the following error below the username field, even though the username appears to be unique:
An object with this field already exists in the current organization
Applies To
- Okta Mastered Users
- Self Service Registration
Cause
The Self Service Registration feature has been enabled for the Okta tenant. When this feature is enabled:
- Okta will enforce uniqueness for all primary email addresses.
- Okta automatically uses the email address as the end user’s username (hence the error in the Username field).
Solution
Make sure that there are no other users with the same primary email address, or recreate the user with a unique email address.
