Connect Mac to Azure AD

We have set up a trial on Azure and would like to test the single Active Directory sign-in functionality so that our Mac and Windows users are authenticated against the Azure AD. However we are not experts in this and are struggling to set the Mac's up. Our domain is on GoDaddy and we have successfully added it to the Azure AD domain list and verified it However we are not sure what to enter when we try and setup the Mac using Network Server in Users & Groups , we have tried using [login to view URL] etc but in all cases it cannot find the server. All our users and groups already exist in the Azure AD domain.
