[EXTERNAL] Re: Strange issue with Redirect endpoint and simple signing

We've validated everything in both directions, and even compared configurations with another University successfully using this application and are still at a loss for what to do next. We've asked the vendor to double/triple check that the certificate that is displayed on the configuration page for the application is the same one that is used when signing the AuthnRequest. We haven't heard back from them yet, but this is the only thing that we can think may be causing this. We don't have this problem with any other SPs that use the HTTP Redirect endpoint with a Simple Signature.

Is there a configuration item anywhere that will disable the Simple Signature validation for a specific SP?

You likely still don't have the right one, or at least you're not getting the metadata accurately changed. You may think you're editing the right file and you're not, for example. Or you might simply be messing up the syntax in some way (wrong use attribute on the KeyDescriptor, that kind of thing).
