Configuring SSOMA with AD

The FortiClient single sign on mobility agent (SSOMA) supports the following features:

• Support for pure Azure Active Directory (AD) mode. SSOMA sends the Azure AD domain and tenant ID to FortiAuthenticator in pure/native Azure AD mode.

• Sends FortiClient UUID and EMS serial number/tenant ID to FortiAuthenticator.

• Sets the SNI field when communicating with FortiAuthenticator.

The following document uses two use cases to illustrate these features. Use case A illustrates a scenario using a local AD. Use case B illustrates a scenario using a pure/native Azure AD or a hybrid Azure AD.

Use case A: local AD

1. Configure FortiAuthenticator:

   1. In FortiAuthenticator, go to Fortinet SSO Methods > SSO > General.

   2. Toggle on Enable FortiClient SSO Mobility Agent Service.

   3. In the FortiClient listening port field, enter 8001.

   4. Toggle on Enable authentication.

   5. In the Secret key field, enter the desired preshared key. In this example, it is Fortinet123!

      

   6. Go to Authentication > Remote Auth. Servers > LDAP.

   7. Add the remote authentication server. In this case, it is the local AD server.

2. In EMS, edit the desired endpoint profile's XML configuration to match the IP address, port, and PSK configured on the FortiAuthenticator:

   <fssoma>
           <enabled>1</enabled>
           <serveraddress>fac0824.local:8001</serveraddress>
           <presharedkey>Fortinet123!</presharedkey>
   </fssoma>

3. After FortiClient connects to EMS and receives the profile changes, go to Settings. Under Advanced, confirm that SSOMA is enabled and the configuration is updated.
4. Under Logging, click Export logs. Confirm that SSOMA sends the FortiClient UUID and EMS serial number/tenant ID to FortiAuthenticator:

Use case B: pure/native or hybrid Azure AD

1. Configure Azure AD and add an enterprise application for FSSO:
   1. Sign in to the Azure AD portal as an administrator. Some configurations require a global administrator privilege.

   2. Create a user and ensure that users may join devices:

      1. Go to Home > Manage Azure Active Directory > View button > Manage > Users > New User. Configure a new user as desired.

      2. Go to Home > Manage Azure Active Directory > View button > Manage > Devices > Device Settings. Enable Users may join devices to Azure AD.

   3. Create an enterprise application:

      1. Go to Home > Manage Azure Active Directory > View button > Manage > Enterprise Applications > New Application > Create Your Own Application.

      2. Select Integrate any other application you don't find in the gallery (Non-gallery). Configure other settings as desired.

   4. Set the newly created enterprise application as a directory reader:

      1. Go to Home > Manage Azure Active Directory > View button > Manage > Roles and Administrators.

      2. In the Administrative Roles list, search for and select Directory Readers.

      3. Add Assignments > Search for the name of the newly created enterprise application > Add button.

   5. Register the enterprise application with the Microsoft identity platform and generate an authentication key:

      1. Go to Home > Manage Azure Active Directory > View button > Manage > App Registrations > All Applications.

      2. Search for and select the newly created enterprise application.

      3. Click Manage > Certificates & Secrets > New Client Secret.

      4. In the Add a Client dialog, set a description and expiry date, then click Add.

      5. Note down the string in the Value column. This value is only visible immediately after creation and will be hidden after you leave this page. You will use this value later.

2. In EMS, edit the desired endpoint profile's XML configuration to match the IP address, port, and PSK configured on the FortiAuthenticator:

   <fssoma>
           <enabled>1</enabled>
           <serveraddress>fac0824.local:8001</serveraddress>
           <presharedkey>Fortinet123!</presharedkey>
   </fssoma>

3. In FortiAuthenticator, configure OAuth:
   1. Go to Authentication > Remote Auth. Servers > OAUTH > Create New.
   2. From the OAuth source dropdown list, select Azure Directory.
   3. In the Client ID field, enter the application ID of the enterprise application that you created. You can find the client ID in Azure by going to Home > Manage Azure Active Directory > View button > (in sidebar) Manage > Enterprise Applications > Search for Application Name.
   4. In the Client Key field, enter the value from the Value column in step 1.e.v.
   5. Enable Include for SSO.
   6. In the Azure AD tenant ID field, enter the tenant ID. You can find this value in Azure by going to Home > Manage Azure Active Directory > View button > Overview > Tenant ID. Click OK.

      

4. Connect the endpoint with Azure AD. On the endpoint, go to Settings > Accounts. Beside Add a work or school account, click Connect.
5. Install FortiClient on the endpoint. Go to Settings and verify that FortiClient has received the SSOMA configuration from EMS.
6. In FortiAuthenticator, go to Monitor > SSO > SSO Sessions. Confirm that there is an entry for the endpoint.
7. In FortiClient, go to Settings > Logging and click Export logs. Confirm that SSOMA sends the FortiClient UUID and EMS serial number/tenant ID to FortiAuthenticator:
