To use HMA with SfB on-premises an on-premises Active Directory federation is required with Azure Active Directory (AAD).HMA allows SfBS & Exchange 2013/2016 (Office 2013 +) to leverage AAD security capabilities like two-factor authentication, or Intune Modern Application Management policies. Hybrid Modern Authentication for Skype for Business Server & Exchange Server 2016Detailed configuration and troubleshooting steps are covered here and here for enabling HMA for Exchange and Skype for Business respectively.Skype for Business Server 20 cumulative update supports Hybrid Modern Authentication (HMA).
Setup Skype For Business Mac May BeSet the Oauth configuration to use this server The SfB server is configured to send authentication requests to Azure AAD. Support for HMA is included in SfB server May 2017 CU5 release, build. Since clients can connect from either internal or external web service URL’s, depending on their network location, both need to be added. The SPN’s need to be in the format of as this is how the requests will be coming from the clients. Since the clients will be making these requests for authentication using the on-premises web service URL’s these web service URL’s need to be configured as Service Principal Names (SPN’s) for the O365 tenant’s AAD SfB service application principal. Azure AAD needs to accept authentication requests from SfB clients. For SfB 2013 clients, a registry entry is required > For SfB 2016 clients, this capability will be on by default. Coding programs from windows for macSfBO tenant has been enabled for MA, see here. Split domain hybrid should be enabled and configured. Therefore all FE servers need direct Internet access to login.windows.net which will allow them to periodically retrieve the AAD certificate against which they will verify the tokens presented by clients. The SfB servers need to trust the AAD tokens presented by the clients. This does not need to be an actual production user of Skype for Business online. One Office 365 tenant user must be assigned a Skype for Business license in order for the service principal for the Skype for Business workload to be created in Azure AD. Ensure SSL offloading is not being used between the load balancer and Exchange servers. Ensure AAD Connect between on-premises AD and the O365 tenant has the “Exchange hybrid deployment” setting enabled in the Optional Features settings of Azure AD Connect. OAuth must be enabled on all Virtual Directories used by Outlook (/AutoDiscover, /EWS, /Mapi, /OAB) Exchange servers must be Exchange 2013 (CU19+) and/or Exchange 2016 (CU8+) The entire on-premises directory must be synchronized to AAD, and all domains used for logon must be included in the sync configuration. Federated Identity with AAD with any on-premises STS supported by Office 365 $lync.ServicePrincipalNames.Add(“ labpool1.shuc.uk/”) $lync=Get-MsolServicePrincipal -AppPrincipalId 00000004-0000-0ff1-ce00-000000000000 Connect to AAD and configure the SPN’s for the SfB Service Principal in Azure AD by running the commands below:- From SfB PowerShell Confirm CU5 or higher is installed with Get-CsServerPatchVersion and confirm the Front End is listed with. EXO tenant has been enabled for MA, see here.Enable Hybrid Modern Authentication for SfB ![]() For Exchange-related URL’s, execute the following command: Check the SSL certificates assigned to Exchange Web Services to make sure all required names are considered for inclusion. Get-OABVirtualDirectory | FL server,*url*> Get-WebServicesVirtualDirectory | FL server,*url* Get-MapiVirtualDirectory | FL server,*url* Get-MapiVirtualDirectory | FL server,*url*,*auth* Ensure OAuth is enabled in Exchange on all the virtual directories Outlook might use. If the EvoSts entry is not present download and execute the latest version of the Hybrid Configuration Wizard. Validate the EvoSts authentication provider is present using the Exchange Management Shell ( Note: this is created by the Hybrid Configuration Wizard) Run Get-MsolServicePrincipal -AppPrincipalId 00000002-0000-0ff1-ce00-000000000000 | select -ExpandProperty ServicePrincipalNames Set-MSOLServicePrincipal -AppPrincipalId 00000002-0000-0ff1-ce00-000000000000 -ServicePrincipalNames $x.ServicePrincipalNames The MAM policy was configured to target Skype for Business & Microsoft Teams. MDM device management was not enabled for the demo user. Enable the OAuth client feature for Windows Outlook: Set-OrganizationConfig -OAuth2ClientProfileEnabled $TrueThe following link here was used to verify the Mobile Application Management policy configuration. Set the EvoSts authentication provider as the default provider by running: Set-AuthServer EvoSTS -IsDefaultAuthorizationEndpoint $true Get-AutoDiscoverVirtualDirectory | FL server,*oauth* Get-OABVirtualDirectory | FL server,*url*,*oauth* Microsoft Authenticator was installed on the same test device for convenience. Microsoft Authenticator App was used for the demo (Other MFA methods are possible and can be selected by the user by logging into Select Profile > Additional security verification. SfBS homed users needs to download and install the Intune Company Portal App. Security Group “MAM_ConditonalAccess_Users” was targeted by the MAM policy.A CA policy was enabled so that Skype for Business/Exchange on-premises Android users are targeted specifically for MFA. All other MAM policy settings were left at their defaults. Users homed on SfBS do not need to be licensed for SfBO. Demo user was licensed for Intune & Azure AD Premium P1. If MA is not enabled on Exchange Server and Exchange Online the user will be prompted to enter credentials and will use whatever authentication protocol is available to authenticate against EWS, example NTLM.Completed in Azure Lab.
