We are trying component space for saml2.0 integration. We were able to successfully run the example projects (web form) sp inititated saml. Tried integrations with okta and onelogin and have no issues.

When we try to use the same approach in our application, receiving an error while processing "SAMLServiceProvider.ReceiveSSO" from Idp(Okta) . = "Exception: ComponentSpace.SAML2.Exceptions.SAMLCertificateException: The X.509 certificate could not be loaded...."

The InititateSSO is happening successfully but seeing issue loading okat.cer from the certifcates folder within the project

Any help to troubleshoot this would be appreciated. Thanks!

It looks like there's an issue with the okta.cer file. From File Explorer, double click on the okta.cer file and confirm that it opens as a certificate file. If it doesn't, try downloading the certificate from Okta again. Let us know if there's still an issue.

I have tried opening the file and saw this error message:

Replaced it with the certificate from Okta and it works fine. Appreciate your quick response. 

Thanks!!
