The last days i implemented the feature to execute cron jobs or any other command from within the WebUI. This may be also used for file system checks for example.
The general SMB/CIFS service frontend and backend has been finished. Currently no Active Directory support has been implemented because i do not have enough knowledge about this feature, also i do not have a Windows Server installation for testing. But the backend has been designed that way to allow users with more knowledge to implement it via community plugin.
