Conflict with SharePoint 2013

[Ladewig, Scott]

Our web folks are working with a vendor to move their public-facing sites from SharePoint 2010 to SharePoint 2013 on Server 2012 R2. We have Shibboleth 2.5.5.1 installed, which they use to
Protect a couple paths on the site.

Worked fine in 2010, but on 2013 they get the 2746 error which usually means some module is getting at the incoming data before Shibboleth and it fails.

They setup a non-SharePoint site on the server and Shibboleth worked normally, so it would appear to be one of the native SharePoint modules. This is a stock SharePoint 2013 install without any 3rd party modules.

Has anyone else run into this issues? I'm not seeing anyone complaining about issues with stock SP2013, so I'm stuck. The vendor handling the sites is going to test the modules to see if they can determine which one is causing the problem, so for now we don't know which one it is yet.
