We do not specifically have a video on mentioned scenario. However, you should be able to achieve it doing the following.
1. Create SSID per tenant
2. Point SSID to either same or different ISE RADIUS server
3. In case of same ISE server, you can identity connection based on SSID and make it authenticate against various AD join point
4. Once traffic tunneled to WLC, you can drop them into an intermediate switch and sort them into different tenant network.
Please keep in mind that WLC does not support multi-tenant management
