Remarks:  If you do not supply a target object at the command prompt, the target  object is obtained from standard input (stdin). Stdin data can be  accepted from the keyboard, a redirected file, or as piped output from  another command. To mark the end of stdin data from the keyboard or  in a redirected file, use Control+Z, for End of File (EOF).    If a value that you supply contains spaces, use quotation marks   around the text (for example, "CN=John Smith,CN=Users,DC=microsoft,DC=com").  If you enter multiple values, the values must be separated by spaces  (for example, a list of group distinguished names).
