Shibboleth Extension not configured

[Nate Klingenstein]

Nicholas,

> Is this a Shibboleth issue or and IIS issue?

Yes(it's a team failure).

> What places should I start looking at for some explanation?

I'm no IIS expeft, but the wiki and the mailing list archives are a great place to start.  You may have a versioning issue, or you may just have the wrong Site ID.
