For a sentinel connector task, when you enable the checkbox "Application connector task(mapping)" a new task will appear in the task monitor, named Sentinel Connector Task (AC). This tasks is used for MetaData browsing and for the ACP Sentinel Mapping. i.e., if you need a map in which you directly creates a message for a Tracked Object in Sentinel, whose definition was imported through the MetaData Browser, by browsing the available Tracked Objects on the Sentinel Server.

This task has no additional settings, it takes it's settings from the Settings of the normal sentinel connector task. If you uncheck this option for the sentinel connector task, it will disappear from the task monitor.
