4.7 Preventing Error Messages to Show the Failure Reason on Browsers

Whenever Identity Server reports a 500 internal error due to an invalid input, the reason for failure is included in the response and visible on the browser.

This might cause a security issue as intruders can use this information to attack against Identity Server and ESP.

Configure the web.xml file for ESP as follows:

  1. Open the web.xml file.

  2. Update the file as follows:

    <welcome-file-list>
       <welcome-file>index.html</welcome-file>
    </welcome-file-list>
    <error-page>
       <error-code>500</error-code>
       <location>/index.html</location>
    </error-page>

    index.html can be any custom page. Similarly, you can configure web.xml for error-code 404 by adding one more <error-page> tag. For information about how to edit a file, see Modifying Configurations in the NetIQ Access Manager 5.0 Administration Guide.
