Error: Simple signature validation (with no request-derived credentials) failed

[Ryan Rumbaugh]

Hi all, I’m working with a vendor (Critical Labs) to try and determine why I’m getting the following exception. Searching the list, I think this occurs when a SP signs an authn request with a different key than what is in metadata. According to the vendor that is not the case, and FWIW I used the SAML authn request validator at https://www.samltool.com/validate_authn_req.php and it checks out.

Any other suggestions on the cause of this? Thanks!
