Called by Lightstreamer Kernel to check that a User is enabled to access the specified MPN device. The success of this method call is a prerequisite for all MPN operations, including the activation of a subscription, the deactivation of a subscription, the change of a device token, etc. Some of these operations have a subsequent specific notification, i.e. NotifyMpnSubscriptionActivation and NotifyMpnDeviceTokenChange.  

Take particular precautions when authorizing device access, if possible ensure the user is entitled to the specific platform, device token and application ID.  

Edition Note: Push Notifications is an optional feature, available depending on Edition and License Type. To know what features are enabled by your license, please see the License tab of the Monitoring Dashboard (by default, available at /dashboard).
