  • * Using DirSync for only provisioning is NOT supported!
  • Note: Passwords are NOT synced. If you want to use your on-premise passwords in Office 365/Azure, you will have to deploy ADFS.Future release of DirSync might support Password Synchronization** Functionality nor a release date have been confirmed by Microsoft. As far as I understood, this sync will not really sync the password, but it will rather use the password’s hash
  • Data loss can occur when re-enabling DirSync after previously having enabled/disabled it. All changes between it was disabled and re-enabled could potentially be overwritten!
  • 3rd party tools e.g. from MessageOps
  • Sign-in assistant contacts Auth Platform.
  • Still need to finalize the image

    8. 8. Directory Synchronization (DirSync)
    9. 9. What is DirSync?“…is a Directory Synchronization engine based on Forefront Identity Manager (FIM) that will synchronize (a subset of) your on-premise Active Directory with Windows Azure Active Directory (Office 365).”
    10. 10. Why use DirSync?• Long term coexistence between Exchange on-prem and Exchange Online• (Easy/quick provisioning*)• Single place for managing identities including: • Users • Groups • Memberships • …• Enabler for Hybrid Deployments (required) • Two-way Directory Synchronization
    11. 11. How does DirSync work? DirSyncActive Directory METAVERSE
    12. 12. Deployment Considerations• Active Directory Health • Prerequisites check (Readiness Tool) • idFix (released 01/03/2013)• Topology • Single Forest? • Multiple Domains?• Security • Firewalls, Permissions• 64-bit only!• (De-)activation time; can take some time to complete• Object filtering required?• SQL Express or Full SQL (+50k objects)
    13. 13. What objects are synced?From AD to Office 365: Office 365 to AD (aka write-back):Write-Back attribute Exchange "full fidelity" featureSafeSendersHash Filtering: Writes back on-premises filtering and onlineBlockedSendersHash safe and blocked sender data from clients.SafeRecipientHashmsExchArchiveStatus Online Archive: Enables customers to archive mail.ProxyAddresses Enable Mailbox: Off-boards an online mailbox back to(LegacyExchangeDN <online LegacyDn> as X500) on-premises Exchange. Enable Unified Messaging (UM) - Online voice mail: This new attribute is used only for UM-Microsoft Lync ServermsExchUCVoiceMailSettings 2010 integration to indicate to Lync Server 2010 on- premises that the user has voice mail in online services.
    14. 14. DEMO Topology DirSync (DS02)Active METAVERSE
    15. 15. Caveats• Be careful when re-enabling DirSync > possible data loss!• In large environments (+50k items) > Service Request needed to raise the object limit in Office 365• Bad Active Directory “health” (object attributes) can influence DirSync’s behavior• Strict permissions might cause issues (e.g. when inheritance flag is removed)
    16. 16. What about…DirSync withoutExchange on-prem?
    17. 17. Some takeaways• Enterprise Admin Permissions required for setup to allow creating of the MSOL_DirSync account + optional Hybrid account and propagate permissions in the forest/domain(s).• Use MIISclient.exe to view operation history and search for objects (SourceAnchor – ObjectGuid)• Filtering is supported but should be treated carefully.
    18. 18. ADFSIntroduction
    19. 19. Federation Primer Multiple IdentitiesChallenges Requirements • Reduce identities (or at least management) to a single source of authority • Allow people to logon into cloud- based solutions with their on- premise credentials • Simplify management • Keep in control
    20. 20. The solution: ADFS• Cross-premises password policies• Simplified user management• Support for two-factor authentication• Access Control using Client Access Policies
    21. 21. Active Directory Federation Services(ADFS)Topologies
    22. 22. ADFS: On Premise Topology Active Directory AD FS 2.0 AD FS 2.0 AD FS 2.0 Server Server Server Proxy AD FS 2.0 Server Proxy Internal user Enterprise DMZ
    23. 23. ADFS: On Premise Topology Active Directory AD FS 2.0 AD FS 2.0 AD FS 2.0 Server Server Server Proxy AD FS 2.0 Server Proxy Internal user Enterprise DMZ
    24. 24. ADFS: Hybrid Topology: IAAS Active Active Directory Directory AD FS 2.0 AD FS 2.0 AD FS 2.0 AD FS 2.0 Server Server Server Server Internal External user Enterprise user IAAS
    25. 25. ADFS: Hybrid Topology: IAAS Active Active Directory Directory AD FS 2.0 AD FS 2.0 Server Server Internal External user Enterprise user IAAS
    26. 26. ADFS: Hybrid Topology: Windows Azure Active Directory AD FS 2.0 AD FS 2.0 AD FS 2.0 Server Server Server LB ENDPOINT IP SEC GATEWAY AD FS 2.0 DEVICE Server CLOUD SERVICE Enterprise Windows Azure
    27. 27. ADFS: Cloud Topology: IAAS Active Directory AD FS 2.0 AD FS 2.0 Server Server Internal External IAAS user
    28. 28. ADFS & 2 Form Authentication• Own solutions e.g. extra PIN integrated in the ADFS pages • Works only with form based authentication • ASP.NET Solution• RSA SecurID Integration• ForeFront UAG
    29. 29. ADFSAuthentication flows
    30. 30. Authentication flows• Different authentication flows, depending on the application and service that you are using.• Office 365 has three different flows: • Passive (Web Applications like e.g. SharePoint & OWA) • Active (Outlook, Exchange Online) • MEX (Lync)
    31. 31. Web (Passive) Authentication Flow WEB
    32. 32. Rich Client Authentication Flow MEX Sign-in assistant
    33. 33. Active Authentication Flow Active
    34. 34. Key Takeaways• ADFS requires a public certificate only for client communications; token signing and encryption can be done with self-signed certificates• Workflow/endpoint is different depending the application you use: Passive (Web)/Rich Client (Lync)/ Active (Outlook)• Troubleshooting is not always easy. e.g. requires understanding how to use tools like fiddler2 etc…
    35. 35. Nice-to-knowsRU1 • Client Access Policy Support (filtering based on IP Address) • New performance counters > monitoring RU2 • RU1 + additional fixes (mainly stability improvements) • Added support for RelayState Parameter
    36. 36. Windows Azure Active DirectoryW.A.A.D. is a modern, REST-based service that provides identity andaccess control for your cloud applications.Already used in:• Windows Azure• Office 365• Dynamics CRM Online• Windows Intune• 3rd party Cloud Services
    37. 37. Windows Azure Active DirectoryW.A.A.D. integrates with domain credentials of local AD via ADFSW.A.A.D. integrates with Access Control Service (a cloud-basedservice that provides an easy way of authenticating and authorizingusers to your web applications and services while allowing thefeatures of authentication and authorization to be factored out of yourcode)W.A.A.D. integrates with Graph API: it allows you to read a subset ofthe entities in the directory: namelyUsers, Groups, Roles, Subscriptions, Tenant Details and some of therelationships which tie those together. The interaction is read-only
    38. 38. Windows Azure Active Directory
    39. 39. Session Takeaways Before deploying DirSync, check your AD and use tools like MiisClient, IdFix and the Readiness Tool WAAD can also be used to extend functionality of your websites Office 365 uses three different authentication flows with ADFS: Active, Passive and MEX. Mind ADFS topologies with regards to High Availability
