Modify an existing JASPI authentication provider

We can modify and configure an existing Java Authentication SPI (JASPI) authentication provider in the cell or in the given security domain using the dmgr console. To modify and configure an existing JASPI authentication provider using the dmgr console, do the following:

1. Click Security > Global security.

2. Click Providers. You also have the option to change the Default provider from the drop-down list.

   We can modify the value of the Enable Java Authentication SPI (JASPI) checkbox to indicate whether or not JASPI support is enabled at a later time.

3. Select an existing JASPI authentication provider to modify.

4. Optional: Enter a textual description of the authentication provider in the Description field.

5. Enter a new package-qualified name of the class that implements the authentication provider interface (javax.security.auth.message.config.AuthConfigProvider) in the Class name field if you wish to change it.

   In the Message layer field, WebSphere Application Server v8.5 supports only the HttpServlet message layer profile as defined in the JASPI specification. We cannot change this value.

6. Optional: Under Custom Properties, select an existing custom configuration property. Click Delete to remove the property, Edit to modify the property, or click New to create a new property. If you select Edit to modify an existing property, we can enter new values for the Name field and Value field if you wish to change them.

7. Click OK or Apply.

We can also modify an existing JASPI authentication provider using wsadmin commands. For more information, read JaspiManagement command group for AdminTask.

Verify that your server has been restarted so the changes to configure the JASPI provider will take effect.
