OMV Directory Service bind to Active directory

Hello All,

I am desperately trying to make OMV integrated with Active directory ,
I found the Directory Service plugin and tried to connect to our Active directory but there is missing user part (or seems to)so i don't know how to bind with the following plugin to our active directory.
In addition if there is better way to accomplish that task please share it
Please advice
Thanks
