This can be configured in Settings → RADIUS Service configuration:

The 'Additional RADIUS Attributes' field should contain the reference to the ldap-group script as shown on the example below:

Important: The group names used for this parameter should not contain "=" sign.
The 'RADIUS LDAP Group mapping' field should contain a mapping rule, which allows members of the specified AD group to have Tunnel-Private-Group-ID attribute equal to some value.
For the example above, if a user belongs to an AD Group named 'Token2_VPN_users', the Filter-ID will be included in the Radius reply as below:
