Office 365 Suite App Integration

Office 365 Suite App Integration

    Set up an Office 365 app integration so that your users can sign into this app using the same credentials that they use for LastPass.

    Notice: Alternatively, LastPass MFA can be used for secure login to Office 365/Azure AD SSO while maintaining Azure AD as the primary Identity Provider. For more info, visit How do I configure my Azure AD account to use LastPass MFA for authentication?

    Part 1 - Add the SSO app to LastPass

    1. Log in and access the LastPass new Admin Console by doing either of the following:
      • While logged in to LastPass, click the active LastPass icon active LastPass icon in your web browser toolbar, then select Admin Console in the menu.
      • Log in at https://admin.lastpass.com with your admin email address and master password.
    2. Go to Applications > SSO apps.
    3. Select Add app in the upper-right navigation (or Search the catalog if you're adding your first app).
    4. Search for and select your app from the catalog (or Add an unlisted app if you can't find your app).
    5. Click Continue, and you are taken to the Set up LastPass section of the app configuration.

      Fastpath: LastPass automatically fills out all required information in the Set up app section for you. Some apps allow you to upload settings in an XML file, while others require you to copy and paste the following information:
      Name in LastPass Value
      Entity ID 
      https://identity.lastpass.com
      SSO Endpoint 
      https://identity.lastpass.com/SAML/SSOService
      Logout URL 
      https://identity.lastpass.com/Login/Logout
      Certificate fingerprint Provided in the Set up app section of the SSO app. If needed, download the LastPass certificate in PEM, DER, or Download metadata (XML) format.
      Certificate fingerprint (SHA256)
      Certificate (PEM)

    6. For the next steps, open a new web browser window or tab. Go to the app's settings to enable single sign-on, and make sure your app recognizes LastPass as the Identity Provider.

    Part 2 - Configure the app in Office 365

    Before you begin: Be sure you have set up and verified a domain before proceeding with the steps below.
    About this task: For detailed instructions, please see Microsoft Office 365 documentation.
    1. Log in to the Microsoft 365 admin center at https://admin.microsoft.com/Adminportal/Home.
    2. Select Settings > Domains in the left navigation.
    3. Confirm that you have a verified domain listed.

      CAUTION: DO NOT add any users at this stage.

    4. In the section where you are asked How do you want to use Office 365?, disable the checkboxes next to Exchange Online and Lync Online unless DNS entries are to be updated.

      CAUTION: Before proceeding, make sure that the domain you will use is not the default domain. Instead, configure the .onmicrosoft.com entry as the default domain.

    5. Note: SSO configuration for Office 365 requires Windows Azure Active Directory Module for Windows PowerShell cmdlets. Download and install cmdlets at https://technet.microsoft.com/en-us/library/jj151815.aspx.

    6. Use the PowerShell Command template and the certificate that you downloaded from the LastPass Admin Console for the next steps.

    Part 3 - Finalize the Office 365 SSO app configuration in LastPass

    1. To configure Office 365 SSO, customize the PowerShell command template as follows:

      • $domain – Enter your company domain in the following format: 
        yourworkdomain.com
      • $issuer – Enter your company domain at the end of the URL, in the following format:
        https://identity.lastpass.com/yourworkdomain.com
      • $certificateFile – Full path and filename of the LastPass certificate file you've just downloaded

    2. Open Powershell as an administrator. Run the following command: 

      $cred=Get-Credential

      Result: You are prompted for administrator credentials.

    3. Enter your administrator login credentials into the dialog that appears on the screen.
    4. Copy and paste the second command to get authenticated on Office 365: 

      Connect-MsolService -Credential $cred

    5. Copy the block of PowerShell commands starting with $domain and ending with $logoffurl. Paste them into your PowerShell window.

    7. Run the following command to enable SSO for your domain: 

      Set-MsolDomainAuthentication -FederationBrandName $domain -DomainName $domain -Authentication federated PreferredAuthenticationProtocol SAMLP -IssuerUri $issuer -Signing Certificate $certificate -PassiveLogOnUri $ssoUrl -ActiveLogOnUri $ecpUrl -LogOffUri $logoffUrl -Verbose

      Powershell command enable SSO in Office365

      Result: You have completed the manual SSO setup for Office 365.

    8. Return to the LastPass new Admin Console.
    9. Back on the Configure app page in the LastPass Admin Console (from Part 1), select Set up LastPass.
    10. LastPass needs to know the app’s URI to the Assertion Consumer Service (ACS) to be able to authenticate users. This is provided by your SSO app.

      ACS
      The URL to which LastPass sends authentication assertions after authenticating a user. It may also be known as Post-Back URL, Reply URL, Single Sign-On URL, or Service Provider URL.
      Step-up authentication (passwordless login)
      Enable this setting if you want to require users to confirm their identity using the LastPass Authenticator app upon each login to this SSO app.
      Remember: Passwordless login for SSO apps only supports authentication using stored biometrics (face or fingerprint) via push notification in the LastPass Authenticator app.

    11. Select Advanced settings.
    12. Click Save & assign users > Users, groups & roles to begin making your selections.
    13. Search for and select your desired users, groups, and/or roles, then click Assign.
    14. Click Save & continue > Finish.
    15. Open PowerShell and execute the following command to add your user: 

      New-MsolUser -UserPrincipalName -ImmutableId -FirstName -LastName -DisplayName -LicenseAssignment -usageLocation

      For more information about adding a user, view Troubleshooting for the Office 365 SSO App Integration.

    16. Log in to the Microsoft 365 admin center at https://admin.microsoft.com/Adminportal/Home.
    17. In your organization's page, select your newly created user.
    18. On the Licenses and apps tab, select Add license.
    19. Enable Assign license to <your user>.

    20. Enable your required license(s) and select Save changes.
    Results: Setup for your SSO app is complete! The LastPass users you assigned to this SSO app can now use their LastPass account to sign in to this SSO app going forward.
