Active Directory

Updated 2 weeks ago by admin

The Active Directory section allows you to configure synchronisation of one or more Active Directory domains with the USS cloud account. The advantage of this is that you can use Active Directory attributes in products that support them, such as Web Security, Email Security and Cloud Application Security. On-premise, Azure AD or hybrid environments are supported.

In the case of the Web Security product, it is still able to log usernames even without synchronising with Active Directory. However, you will not be able to enforce rules based on Active Directory attributes without synchronisation on on-prem or hybrid AzureAD domains.

On-Premise Active Directory sync

AD synchronisation uses a locally-install AD Connector service, which pushes objects securely to the USS Cloud.

To view and edit your AD syncs, visit your USS Dashboard and click ProductsSettingsActive Directory.

Your existing Active Directory listings will be shown.

To add new domain, click the button. Enter the details of your new domain into the form that's displayed.

Domain

A description for the domain. Typically your Active Directory domain name, for example: ourdomain.local

Source name/IP

Enter the DNS name of the domain, or the name or IP address of a specific domain controller. Leave empty to use the server where the AD Connector is installed.

Protocol

Select the protocol to use for retrieving data from the domain controller(s). LDAPS utilises SSL/TLS encryption.

Credentials

Enter credentials for connecting to the domain controller(s).

A user with read access to Deleted Objects Container is required.

This can be entered in UPN format e.g. user@domain.local or using LDAP notation e.g. CN=ldapsync,CN=Users,DC=ourdomain,DC=local

Base DN

Enter the DN to use as the root of the search, or leave blank to sync the entire domain.

NetBIOS

Enter a specific NetBIOS name to use or attempt to detect NetBIOS domain automatically.

E-mail addresses

Select whether or not to import email addresses from Active Directory and optionally set the attribute containing the email address.

Click to add the domain to the list.

If you block outbound connections then it may be necessary to open TCP port 443 from the server the AD Connect agent is installed on, to the AD Connect web service.

You should now proceed to download and install the AD Connector service on your local network.

AzureAD or Hybrid

You can link an Azure Active Directory to USS, in addition to or instead of an on-premise Active Directory sync. To do so, just choose Azure Active Directory from the dropdown menu.

AzureAD synchronisation is not compatible with the Web Security product unless an on-premise AD is also synchronised with Azure. The Web Security product and user authentication features rely on samaccountname attribute which is not available with a native AzureAD.

You will need your Azure tenant name (which will be in a form similar to name.onmicrosoft.com), and you'll be required to approve USS for read access to the Azure directory. You'll need an administrator account to grant that access.

Options

Domain

This is a friendly name to identify the AzureAD connection.

Source name/IP

This is the Microsoft tenant name, e.g xxx.onmicrosoft.com entered in full.

Email addresses

This option can be used to exclude email addresses from being synchronised. It is also possible to specify a custom attribute that contains the email address. Email addresses are used if the Cloud MFA product or Email Security product is licensed.

Default Prefix

This specifies the default telephone prefix for synchronised users. This is required if the Cloud MFA product is licensed.

Phone numbers

This option can be used to exclude phone numbers from being synchronised. It is also possible to specify a custom attribute that contains the phone number. Phone numbers are used if the Cloud MFA product is licensed.

Only synchronise users with this attribute set

This advanced option lets you specify a User Property from the Graph API that must be present with the given value(s) in order for the user object to be synchronised. You may specify multiple values using a semi-colon ; separator, if required e.g. attribute name = officeLocation value = London;Paris

Only synchronise groups with this attribute set

Coming soon. Please ask your service provider to configure this option manually if required.

Once the domain is added, a new browser window will open and redirect you to Microsoft login page for the specified tenant in the Source name/IP option.

You must sign in with an administrator account for the tenant and grant consent for the USS service to read directory data from Azure AD.

Click Accept to continue. You can now close the browser tab and return to the USS dashboard.

It can take up to 15 minutes for the Azure AD objects to synchronise with USS. Until then, the domain will show as having 0 objects in the list. After the synchronisation has complete, the available objects will be displayed. If you are also synchronising email addresses for Email Security or email and phone numbers for Cloud MFA, this can take several minutes longer.

Deleting a Domain Connection will remove the objects from any product rules that were using them, for example Web Security Rules.
