Before installing DirSync
 Active Directory remediation
 IdFix
 Forest functional level
 Windows Server 2003
 Multiple forests
 Not DirSync
 Azure AD Sync or Forefront Identity Manager 2010
 Directories other than Active Directory
 Not DirSync
 Works with Office 365 – Identity program
IdFix – DirSync AD Remediation
What errors does IdFix look for?






Duplicate proxyAddresses
Invalid characters in attributes
Over length attributes
Format errors in attributes
Use of non-routable domains
Blank attribute that requires
a value


mailNickName
proxyAddresses
sAMAccountName
targetAddress
userPrincipalName
DirSync topology and number of servers
 A domain controller collocated install isn’t
recommended
 But it is supported and you can install DirSync on the DC
 One server is most common
 DirSync installs SQL Express for replication data
 You can install with dedicated SQL Server and can use HA for SQL Server
 Consider using Azure
 To avoid any on-premises servers you can deploy to Azure IaaS
 Use the DirSync road map
 Read the docs, but skip the Microsoft Deployment Readiness Toolkit
DirSync installation and review
 Be aware of directory object limits
 A new tenant can sync up to 50,000 directory objects
 Register a vanity domain and it is increased to 300,000 objects
 Add DNS domains to Office 365
 Add these prior to syncing to preserve UPN
 Sync now
 Expect about 1 hour per 5,000 objects
 Check event logs
 EventVwr
 Password expiry for the sync account
 Assign Office 365 licenses
Other DirSync considerations
 High availability
 Can Backup and reinstall
 Filtering DirSync
 By OU
 Security of hashes
 One way hashes (of hash)
 Not reversable
 Sent to Azure AD on SSL
Password hash sync security
 We typically get questions about the security of synchronizing
passwords from banking and finance customers
 The password hash that we get from AD is not reversible to get the
users password
 Hashes are mathematical functions that are nearly impossible to
reverse. The result of the hash algorithm is called a digest
 We further process it with a one way hash SHA256 algorithm
 We connect over SSL to the Azure AD service and send the resulting
hash of the hash
 This enables Azure AD to validate the users password when they log in

Choosing between DirSync and AAD Sync
Beta available

 Includes password hash sync
 Includes sync from multiple forests including
 Includes password write-back with Azure AD

Premium license
Can filter objects by OU
Supports use of dedicated SQL Server install or
SQL Express
The setup wizard can be run multiple times for
configuration changes
Released and supported in production

merging duplicate users in these forests
** In addition to AD, can sync from LDAP v3,
SQL Server and CSV data
** Enables selective OU sync with using UX in
the setup. Compared to DirSync which requires
PowerShell configuration
** Enables transforming of attributes using UX
in the setup
Planned to replace DirSync in the future
Preview cannot be upgraded to later release
** NOT IN BETA

Backup for
Federated Sign-In
This new backup option for
Office 365 customers using
federated sign-in provides the
option to manually switch your
domain in a short amount of
time during outages such as onpremises power loss, internet
connection interruption and any
other on-premises outage.
ADFS is Also Easy
 Use trained and experienced deployment staff
 Use Azure AD Connect Tool
 https://microsoft.sharepoint.com/teams/OfficeOnRamp/wiki/Pages/Azure-ActiveDirectory-Connect-Tool.aspx
 Read all the TechNet Deployment Guidance
 http://technet.microsoft.com/en-us/library/jj205462.aspx
 Only implement the Office 365 requirements
 The only certificate required is the SSL certificate
 Prepare with firewall update permissions

How to choose an identity model
?
Change between models as needs change
 Cloud Identity to Synchronized Identity
 Deploy DirSync
 Hard match or soft match of users
 Synchronized Identity to Federated Identity
 Deploy AD FS
 Can leave password sync enabled as backup
 Federated identity to Synchronized Identity
 PowerShell Convert-MsolDomainToStandard
 Takes 2 hours plus 1 additional hour per 2,000 users
 Synchronized Identity to Cloud Identity
 PowerShell Set-MsolDirSyncEnabled
 Takes 72 hours and you can monitor with Get-MsolCompanyInformation
Choose the simplest model for your needs
 This is our recommendation
 Cloud Identity is the simplest model
 Choose cloud when
 You have no on-premises directory
 There is on-premises directory restructuring
 You are in pilot with Office 365
Choose synchronized identity if you have
an on-premises directory
 Password hash sync means federation is not required
just to have the same password on the cloud




Same sign-on – the username and password
is the same in the cloud as on-premises
Single sign-on – you log on to the PC and
no password is required for cloud services
Save credentials for later uses
Windows Credential Manager
Outlook does not support Single sign-on
 Choose password hash sync unless you have one
of the scenarios that requires federation
Scenarios for choosing federation
Existing infrastructure
1. You already have an AD FS Deployment
2. You already use a Third Party Federated Identity
Provider
3. You use Forefront Identity Manager 2010
Scenarios for choosing federation
Technical requirements
4. You have Multiple Forests in your on-premises AD
5. You have an On-Premises Integrated Smart Card or
Multi-Factor Authentication (MFA) Solution
6. Custom Hybrid Applications or Hybrid Search is
Required
7. Web Accessible Forgotten Password Reset
Scenarios for choosing federation
Policy requirements
8. You Require Sign-In Audit and/or Immediate Disable
9. Single Sign-On minimizing prompts is Required
10. Require Client Sign-In Restrictions by Network Location
or Work Hours
11. Policy preventing Synchronizing Password Hashes
to Azure AD
