Configure a custom user name mapper

Before you begin

Review the conceptual information and attribute options for a user name mapper. See Configuring a Custom User Name Mapper.
If automatic realm restart is enabled, you do not need to restart WebLogic Server for non-dynamic changes made to the security providers to go into effect. See Enable automatic realm restart and Using Automatic Realm Restart.

To use a custom user name mapper with the WebLogic Identity Assertion provider (Default Identity Asserter):

If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
On the Security Realms page, select the name of the realm you are configuring (for example, TestRealm).
Expand Providers > Authentication and select the name of the Default Identity Asserter.
Expand Configuration > Provider Specific.
In the User Name Mapper Class Name field, enter the name of the implementation of the weblogic.security.providers.authentication.UserNameMapper interface.
Click Save.
In the Change Center, click Activate Changes. If automatic realm restart is enabled, you do not need to restart WebLogic Server for updates to take effect.
