When the Web application environment is configured with an authentication scheme other than basic, remote portlets might display the following exception:

ServletException in:/sas/portlets/portletName/display.do] 
  Method must be executed before this function is called'

When basic authentication is used, the Portal attempts to pass authentication credentials to the remote application in the URL. When an authentication scheme other than basic is used, remote Web applications might incorrectly interpret the header and expect authentication credentials in the URL. This will cause the remote application to fail.

When an authentication scheme other than basic is used, remote applications must be configured so that they do not expect authentication information in the URL.

If the authentication is done by a front-end HTTP server, and the authentication is not basic, then URLs that are used in the portlet.xml for the remote portlet should bypass the front-end HTTP server and directly reference the Web application server port.

Select the Hot Fix tab in this note to access the hot fix for this issue.

After the fix is applied, the Portal will ignore any authentication headers other than basic, and will not attempt to pass them along to the Web application referenced by the remote portlet.
