The method may also include using a plurality of virtual delivery appliances to receive connection requests from the client devices, with the connection requests including connection leases having associated resource entitlements the client devices are respectively permitted to access, and request validation of the connection leases from the computing device. At the computing device, responsive to validation requests from the virtual delivery appliances, the connection leases may be compared to the updated published resource entitlements and validated based thereon. At the virtual delivery appliances, the client devices may be provided with access to virtual sessions corresponding to the published resource entitlements responsive to the virtual session request validations from the computing device.
