How-To Question: getting the user ID from authentication

[Gerry Kaplan]

I have a sitemap resource that transforms into HTML. I am utilizing the
Authentication Manager. The XSL for the page needs to have the ID of the
currently signed on user. A point to remember is that the resource is also
used for public pages, where the user is NOT signed in. 

The only solution I could come up with is as follows, but it seems like a
kludge. It needs to process two additional transformers! Does nayone know if
there's a better way to do this?

<map:resource name="layout">
    <map:act type="auth-loggedIn">
        <map:parameter name="handler" value="imweb-auth-handler"/>
        <map:act type="auth-protect">
            <map:parameter name="handler" value="imweb-auth-handler"/>
            <map:transform src="presentation/add-authentication-part.xsl"/>
            <map:transform type="session"/>
        </map:act>
    </map:act>
    <map:transform label="layout" src="presentation/page-to-html.xsl" />
    <map:transform label="relative" src="presentation/relativize-links.xsl">
        <map:parameter name="currentPath" value="{request:requestURI}"/>
        <map:parameter name="basePath" value="/imweb/public/"/>
    </map:transform>
</map:resource>
