Hi Team,

I wanted to remove ADFS based authentication and wanted to use only AD connect.

Microsoft the O365 authentication which is working with PHS (Password Hash Synchronization) in AD Connect will stop Dynamics CRM Authentication for IFD deployment

Anyone has done this kind of implementation for Dynamic CRM IFD deployment?

Hi Sushma,

unfortunately, CRM on premise does not support a direct federation with Azure AD.

It is a non-documented / tested scenario by Microsoft.

To connect CRM on premise with other IDPs or services an ADFS is and will remain mandatory. (Please see the software requirements: learn.microsoft.com/.../software-requirements-for-microsoft-dynamics-365-server

Based on the software requirements a local domain controller is required to create the Users in CRM properly.

As Authenticationmethods we only accept Windows Authentication for Claim Based and SAML:Password for IFD.

You can synchronize your users to a local domain controller to create themm properly in CRM.

Aswell you can connect the ADFS to O365 authentication.

Anyways an ADFS will remain requirement.
