You can use SSO with a proxy server in your Application Engine environment. To enable this optional approach, edit the web.xml file on the WebLogic Server.
To edit web.xml for SSO

<init-param>
<param-name>perimeterChallengeMode</param-name>
<param-value>true</param-value>
</init-param>
These parameter values are used to modify one or more elements of the native URL that Workplace sees on a request. Wherever the value of an SSO proxy host element in the URL request is different from the equivalent information for the host where Workplace is deployed, then you must set the corresponding sso* parameter for that element in the URL to the value for the SSO proxy host.
