Greetings
Faced with the problem of SSO authorization. Using the plugin "Authentication: SAML2 Single sign on" (moodle.org/plugins/auth_saml2)
I am using the latest version of the moodle system.
Authorization works together with the overdrive (overdrive.com) service.
To configure the plugin, I requested the data on the certificate from technical support.
They sent me the idp metadata (https://auth.overdrive.com/v2/external/saml/metadata?websiteId=340126&ilsName=joeyedusaml), which I entered in the plugin settings. I sent them my certificate https://staging.dingotalk.com/auth/saml2/sp/metadata.php (which the plugin generated) and a link (https://staging.dingotalk.com/auth/saml2/sp/saml2-acs.php/staging.dingotalk.com) for the log-in.
When I try to use authorization, I get an error: "SAML2 exception: BADREQUEST('%REASON%' => 'Invalid message received to AssertionConsumerService endpoint.')".
Maybe someone will have any thoughts on this?
Thanks for any help!
