local.ERROR: Saml2 error ["invalid_response"]

[dbeyzad]

I am receiving the following in the laravel log after the SAML is returned from the IDP. In chrome using the SAML inspector tool everything looks fine.

No login event is fired within laravel.

Any suggestions?

Thank you

use a debugger or a classy var_dump and trace this https://github.com/onelogin/php-saml/blob/7a87f05681c57d121b2da81768532ab7197b1a84/lib/Saml2/Response.php#L85

@aacotroneo Thanks. I managed to fix it, it was a certificate issue.
I have this fully working now with laravel 5.3

HI,

I am facing the same issue. What is the certificate issue? can you please explain in details, so that I may get some clue

Hi, Finally I have resolved this issue.

The "x509cert" from idp configuration in saml2_settings.php was not matching with the IDP server crt. I copied the IDP .crt content to the x509cert variable and it worked :)
