Federation Issues - No protocol handlers?

Hi All, It's been a number of years since I've federated a domain with Entra, i'm flipping this back in a home environment to complete some testing. Would appreciate some troubleshooting thoughts. ...

    I'm running into the same issue with v2.4.27.0 of Entra Connect. v2.3.8.0 works fine.

Please check on follow:

 

  • IdP Initiated Sign-On Page: Ensure that the IdP-initiated sign-on page is enabled. You can do this by running the following PowerShell command:
Set-AdfsProperties -EnableIdPInitiatedSignonPage $true

Verify by 

Get-AdfsProperties
  • Protocol Handlers: Make sure that the protocol handlers are correctly registered for the path /adfs/ls/. You can check this in the ADFS management console under the "Authentication" tab.
  • Relying Party Trusts: Ensure that the relying party trusts are correctly configured and that they are not pointing to an incorrect endpoint.
  • Firewall and Ports: Double-check that your firewall settings and port forwarding are correctly configured to allow traffic to the ADFS server.
  • Event Logs: Look at the ADFS event logs for more detailed error messages that might give additional clue.
