1 RSA SecurID Access Configuration for Microsoft Office 365 STS (Secure Token Service) Last Modified: April 17, 2017 RSA SecurID Access offers two methods to integrate with Microsoft Office 365. Both solutions integrate with your organization s Microsoft Azure AD to provide your users with a more consistent sign-in experience. Configuring either the Microsoft Office 365 or Microsoft Office 365 STS connectors provide for single sign-on (SSO) enabled users to use their Active Directory corporate credentials to access their services in the cloud and their existing on-premises resources. For guidelines to help determine which connector to use for the Office 365 applications in your deployment, see the topic Microsoft Office RSA SecurID Access Application Connector Overview on RSA Link. Complete the following procedure to configure the Microsoft Office 365 STS connector. Before You Begin Acquire an administrator account to both RSA SecurID Access and Office 365 Enterprise. Acquire a public trusted SSL certificate. Self-signed SSL certificates are not supported. Note: Refer to Microsoft s guides: Enable your tenant for Modern Authentication (ADAL) 1. Use PowerShell to enable your Exchange Online service for modern authentication as described here and Skype for Business Online as described here. SharePoint Online is already enabled. 2. Enable any Office 2013 users to use modern authentication if step-up policy is to be enforced as described here. Overview of steps 1. Configure Office 365 with a federated domain. 2. Setup Active Directory (AD). 3. Setup directory synchronization.(components: Microsoft Online Services, Window Azure Active Directory Module for Window PowerShell, Azure AD Connect, Skype for Business Online Windows Power Shell Module) 4. Configure RSA SecurID Access Microsoft Office 365 STS connector. 5. Configure federation partnership using PowerShell. 6.

A user might either be represented only once across all forests or have a combination of enabled and disabled accounts. The user might also be represented as a contact in some forests.

10 10. On the Domain/OU Filtering screen, you can select to sync all OUs to Azure AD, or unselect all and select specific OUs. 11. Uniquely identifying users allows you to define how users from your AD DS forests are represented in Azure AD. A user might either be represented only once across all forests or have a combination of enabled and disabled accounts. The user might also be represented as a contact in some forests. Note: SOURCE ANCHOR - The attribute sourceanchor is an attribute that is immutable during the lifetime of a user object. It is the primary key linking the on-premises user with the user in Azure AD. Since the attribute cannot be changed, you must plan for a good attribute to use. A good candidate is objectguid. This attribute is not changed, unless the user account is moved between domains. 10 Copyright 2017 EMC Corporation. All Rights Reserved.

Add an Identity Source In order to use any clients that use the active endpoint, such as mail clients that use the ActiveSync protocol, or other clients that simply use a username & password, then an Identity Source that uses the mail attribute as the User Tag is required. 1. In the RSA SecurID Access Administration Console, click User > Identity Sources. 2. Select Add an Identity Source or select Edit to view an existing Identity Source. 3. On the Identity Source Details page under Connection Settings, verify the value of usertag field.

Known Issues and Workarounds Rich Clients and Step up Applications, such as the ios and Android mail apps that connect to Microsoft resources using the ActiveSync protocol and rich clients with ADAL

23 Known Issues and Workarounds Rich Clients and Step up Applications, such as the ios and Android mail apps that connect to Microsoft resources using the ActiveSync protocol and rich clients with ADAL disabled will not support step up. This will prevent end users from logging in to clients when a policy is configured to require additional authentication. Resolution: Administrators can configure policies based on the user agent header to identify whether the request is from a rich client which does not support additional authentication, or from one that does, and allow access/deny access based on their requirement. Create a new policy under Access > Policies and apply the policy to the Microsoft O365 STS application. o If User Agent Contains "MSOIDCRL", then specify an action ie., Allow/Deny (Applicable for Word, Excel, PowerPoint, Skype, non active sync clients) o If User Agent is NULL, then specify an action ( Applicable for Outlook, Active sync clients ) Note: Contact RSA support for additional Rich Client header options. 23 Copyright 2017 EMC Corporation.

24 Office 2013 Rich Clients not prompting for credentials A domain-joined user using a rich client will initially login, but if the user signs out of the rich client, they won t get prompt to sign-in. Resolution: Add a new DWORD value to the registry NoDomainUser and set the value to 1. For full details refer to Microsoft link How to get re-prompt for Outlook Password on a Mac Removing the keychain entries for your configured accounts, and have Outlook recreate them. 1. Quit Outlook before going into the Keychain. 2. Open the Keychain Access utility (in the Applications > Utilities folder). 3. Select the login keychain. 4. Search for the service (ie, the server name) of the account you have configured in Outlook. 5. Select the displayed keychain entry, and press the Delete key to remove it. 6. Then LogOut or restart your Mac. 24 Copyright 2017 EMC Corporation. All Rights Reserved. GLS
