Questions Regarding User Profile Policy Configuration for Email Address Login
Hi Okta Community,
We currently use the Last Name.First Name format as the Okta login identifier. To allow users to log in using their email addresses as well, we are adding a custom attribute and configuring a User Profile Policy.
Currently, many user attributes are configured with the following source priority:
- Source priority: Inherit from profile source
1. CSV Directory
2. Active Directory
We have two questions regarding this configuration.
①Impact of Changing the Source Priority for the Custom Attribute
If we configure only the newly added custom attribute with the following source priority, would this affect any other attributes or existing user data?
- Source priority: Override profile source
1. Active Directory
2. CSV Directory
②Import Requirements After Adding a Custom Attribute
After adding the custom attribute, is it necessary to perform either a full import or an incremental import from Active Directory or CSV Directory in order for the attribute value to appear in the user profile?
Thank you very much for your support.
We look forward to your guidance.

Thank you for posting on our Community page!
You are asking whether configuring a newly added custom attribute with a different source priority (Override profile source with Active Directory first, then CSV Directory) would affect existing attributes, and whether an import is required after adding the custom attribute for it to appear in user profiles.
Short answer: Configuring source priority at the attribute level affects only that specific attribute and does not impact existing attributes or their data. However, an import may be necessary depending on how you populate the custom attribute values.
Root Cause:
Okta supports attribute-level sourcing, which allows individual attributes to have their own source priority independent of the profile master priority. When you configure source priority for a specific attribute using the "Override profile source" setting, that configuration applies only to that attribute. Other attributes continue to follow their existing source priority settings (in your case, "Inherit from profile source" with CSV Directory first, then Active Directory).
Solution:
Question ①: Impact of Changing Source Priority for the Custom Attribute
Configuring the custom attribute with "Override profile source" and a different priority order will not affect any other attributes or existing user data. Here's why:
Question ②: Import Requirements After Adding a Custom Attribute
Whether you need to perform an import depends on how the custom attribute values will be populated:
Best Practice:
After adding the custom attribute to your User Profile and configuring its source priority, perform an incremental import from Active Directory (your highest priority source for this attribute) to populate the custom attribute values for existing users. This ensures all users have the attribute value available for use as a login identifier.
