Follow the steps below to write a custom authentication handler.
- Implement the custom handler according to the above example.
- Build the class and copy the JAR file to
<PRODUCT_HOME>/repository/components/lib/folder. - Log in to the management console and click Service Bus and then click Source View in the Main menu.
In the ESB configuration that opens, the following line appears. This is the current authentication handler used in App Manager.
Code Block language xml <handler class="org.wso2.carbon.appmgt.gateway.handlers.security.saml2.SAML2AuthenticationHandler"/>
Replace the above line with the handler that you created to engage your custom handler to the App Manager instance. According to this example, it is as follows:
Code Block language html/xml <handler class="org.wso2.carbon.appmgt.gateway.handlers.security.saml2.CustomAPIAuthenticationHandler"/>
