Invalid signing certificate in the metadata file when applying changes to SAML Qlik Sense virtual proxy

[Damien_Villaret]

When trying to apply changes to a virtual proxy set up with SAML authentication, the error "invalid signing certificate in the metadata file" appears.

Environments:

• Qlik Sense Enterprise on Windows 

As the message says, the certificate provided in the IdP metadata file is invalid, the most common reason is that it has expired.

Example:

<KeyDescriptor use="signing">
<KeyInfo xmlns="http://www.w3.org/2000/09/xmldsig#">
<X509Data>
<X509Certificate>
MIIC8DCCAdigAwIBAxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxIDxibeHXAszya
</X509Certificate>
</X509Data>
</KeyInfo>
</KeyDescriptor>

By copying the certificate from the IdP file and decoding it, you will be able to see the expiration date.
For example, a website such as https://www.sslshopper.com/certificate-decoder.html can be used to decode the certificate.
