How to delete inactive computers using ADManager Plus

Hi,

I am currently in the trial offer for ADManager Plus, and I am trying to mass delete inactive computers in Active directory.

I used the ADManager Plus report generator to generate a list of computers that's been inactive for than 120 days.

The list is in the following format:

Computer Name
Bob computer
Ann computer

I exported the .csv file and when I tried to import the file for deleting, it gives me the following error:

"The following attribute(s) Bob Computer in the header is/are not authorized for this user."

I thought it might be a permission issue but I tried deleting it manually one by one and it worked so my guess is that my .csv format is wrong. Can you give me some insight as to what I am doing wrong or what the format of the .csv file should be?

I also found the following topic/link via google, but I am unable to find the attribute "sAMAccountName" in the reporting feature.
