Configuring the SP for sites with multiple IIS bindings

[Wessel, Keith]

Hi, all,

We've got an SP admin who's having problems with an IIS site that has multiple bindings (IIS bindings, that is) all protected by Shib. The site is running a multihome CMS configured to serve different content depending on the hostname used to access it, all under a single IIS site. The SP seems to be requesting responses be sent to the primary hostname of the site and returning the user to a page on the primary hostname regardless of which hostname was used to access it initially.

I had the admin add <Alias> elements to his site element:

            <Site id="2" name="site.illinois.edu" scheme="https" port="443">
                <Alias>alias.site.illinois.edu</Alias>
            </Site>

And the corresponding request map:

        <RequestMap>
            <Host name="site.illinois.edu">
                <Path name="cms/login" requireSession="true" authType="shibboleth" />
            </Host>
            <Host name="alias.site.illinois.edu">
                <Path name="cms/login" requireSession="true" authType="shibboleth" />
            </Host>
        </RequestMap>

But still, a user visiting alias.site.illinois.edu gets sent to the IdP and returned to site.illinois.edu instead.

Are we missing something?
