Fix Recommendation

On the BlackBerry UEM, do the following:

Configure constrained delegation for the Microsoft Active Directory account to support single sign-on:

1. Log in to the BlackBerry UEM host server and use the Windows Server ADSI Edit tool to add the following SPNs for BES12 to the Microsoft Active Directory account:
- HTTP/<host_FQDN_or_pool_name> (for example, HTTP/domain123.example.com)
- BASPLUGIN111/<host_FQDN_or_pool_name> (for example, BASPLUGIN111/domain123.example.com)
Note:
- If high availability is configured for the management consoles in a UEM domain, specify the pool name. Otherwise, specify the FQDN of the computer that hosts the management console.
- Verify that no other accounts in the Microsoft Active Directory forest have the same SPNs.
2. Open "Microsoft Active Directory Users and Computers".
3. In the Microsoft Active Directory account properties, on the "Delegation" tab, select the following options:
- Trust this user for delegation to specified services only.
- Use Kerberos only.
4. Add the SPNs from Step 1 to the list of services.

Configure single sign-on for UEM:
Note:
- When configuring single sign-on for UEM, it is configured for the management console and UEM Self-Service.
- If enabling single sign-on for multiple Microsoft Active Directory connections, verify there are no trust relationships between the Microsoft Active Directory forests.
1. Log in to the BlackBerry UEM console.
2. Select the "Settings" tab on the left pane.
3. Click the "External integration" tab on the left pane.
4. Click "Company directory".
5. In the "Configured directory connections" section, click the name of a Microsoft Active Directory connection.
6. On the "Authentication" tab, select the checkbox next to "Enable Windows single sign-on".
7. Click "Save".
8. Click "Save" on the pop-up window.
Note: UEM validates the information for Microsoft Active Directory authentication. If the information is invalid, UEM prompts to specify the correct information.
9. Click "Close".
10. Restart the UEM services on each server that hosts a UEM instance.
