The SAML response signature failed to verify.

I am getting this error randomly like every one / two days. if I change something in web.config file in service provider project/ then it will start working again but it again failed in next one or two days

what can be the problem here ?

The log includes:

The X.509 certificate with subject name CN=dexcom.hlxbureau.com, C=NO, serial number 0D2EBAF0 and thumbprint A4ADD47B8AB3CA043F6A7652835E3255E8DAAD2E is being used to verify the XML signature.
The X.509 certificate with subject name CN=www.idp.com, serial number 74F0EBFE22358DB8433138F9558C9AF9 and thumbprint A6A4AE4E0B378EC73678E5812690AF50E3EC3769 is embedded in the XML signature.

What this means is that the dexcom.hlxbureau.com certificate is configured in your SP to be used to verify signatures from the IdP. However, the www.idp.com certificate is embedded in the XML signature from the IdP.

Please ensure that the correct certificate is configured at the IdP and that this isn’t being changed.

Please see below log

both certificate are same still it says Failed to verify Signature

Our Identity Provider has provided certificate.

I want to test that certificate with the demo application

so when I replace that certificate with idp.cer file in both service provider and identity provider demo project it gives error

Can you let me know how can I test the certificate? with demo application


If the www.idp.com test certificate is the correct one, update your service provider’s saml.config to specify this as the partner certificate file. For example:


<PartnerIdentityProvider
Name=“…”







The idp.cer file will be used to attempt to verify XML signatures from this identity provider.

Hello,

dexcom.hlxbureau.com is the certificate that I need to use.

So in the demo application
1 Identity provider - I am modifying idp.cer by opening it to notepad, update the certificate code and save it
2 Servuce Provider - I am modifying idp.cer by opening it to notepad, update the certificate code and save it

so that why I am updating existing cer file but I am getting above error

Do you have the private key for the dexcom.hlxbureau.com certificate?

The identity provider would need this to sign the SAML response.

If you do, you have to update the idp.pfx which is the local certificate for the identity provider. It doesn’t use the idp.cer file.

The identity provider signs with the private key (eg idp.pfx) and the service provider verifies with the corresponding public key (eg idp.cer).
