• Mappings
• Okta Attributes
• Application Username

In order to have the application username update automatically, ensure that one of the following conditions is met:

1. Provisioning is enabled.
2. The Application Username format is set to Custom and is not using deprecated expressions or non-working expressions.  

NOTE: Use the corresponding mappings for the required username format. Examples of this are listed below: 

1. 1. 1. Okta Username ( user.login ).
      2. Okta Username Prefix ( String.substringBefore(user.login, "@") ).
      3. Email ( user.email ).
      4. Email Prefix ( String.substringBefore(user.email, "@") ) .
      5. Any unique Okta attribute can be referenced on the username by using user.variableName (for example, user.title, user.employeeID, etc.).

3. The application has more than one attribute mapped as Create and Update from Okta to the Application.

If none of the conditions are satisfied, the application username will not update automatically. However, it can be updated manually by selecting the Sign On tab of the application and clicking on the Update Now button. This process will update the application username of all users assigned to the application. It is not possible to exclude users.
