I’ve been setting up Single Sign On with Active Directory for our application according to this instruction:

https://auth0.com/docs/authenticate/identity-providers/enterprise-identity-providers/azure-active-directory/v2#register-your-app-with-azure-ad

However, after redirect to the Microsoft page i get this error:

Cannot read property ‘tenant_id’ of undefined

In my Auth0 Dashboard under

Monitoring > Logs

i found this error log:

What i’ve been trying so far:

  • Created a new Auth0 account and connect the sample React Login application (https://github.com/auth0-samples/auth0-react-samples/tree/master/Sample-01) provided by Auth0 to the same Active Directory endpoint (works :white_check_mark:)

  • Connect our Development Auth0 account to Active Directory using the Auth0 React sample app (doesn’t work :x:)

  • Connect our React development application to the Active Directory Endpoint (throws error as shown above :x:)

  • Playing around with different Callback URLs. Added some URLs and Routes to the existing http://localhost:3000 (doesn’t work :x:)

I think this error was caused by wrong settings in our Auth0 account since creating a new account doesn’t show any problems. I also don’t see any issues caused by setting up the Active Directory application.
