Logging into Azure AD only computer with on-prem AD based certificate on smart card

We're making the move to deploying Azure AD only devices but we're running into real issues getting authentication to work using our smart cards (we're a federal gov agency) for our user accounts which come from on-prem AD. While we do have MS resources we're working with we seem to be having a hard time finding the right MS resources that can assist us in getting all the components configured correctly (in Azure AD etc) for this to work (or determine if it is even possible). So I wanted to see here if there may be some recommendations on resources that we might be able to leverage to get this effort moving forward? Any help is appreciated. Also all on-prem devices are Hybrid AD joined and everything is co-managed and there are no issues there.

Thanks,

Jamie

      Hey Roy,
      Thanks for this, that might be what we need, this has ended being a real difficult hurdle for us to get over. Authenticating/logging into the Azure AD only device works fine with an Azure AD only user account, but using our existing on-prem accounts has not been something we've been able to get to work at all and we're also moving forward with some special projects that utilize HoloLens's so it's a growing need for us to figure this out. I really appreciate the info.

        Just to make sure there's no ambiguity here, this is completely expected and by design. You must use an AAD user identity to log into an AAD joined Windows endpoint. You can sync your on-prem AD accounts to AAD thus making those accounts "hybrid" user accounts that exist in both AD and AAD and which makes it seem like you are using an on-prem AD account to login, but you cannot directly use an on-prem AD account/identity.
