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 distinguished names). 

The special token $username$ (case insensitive) may be used to place the SAM
account name in the value of a parameter. For example, if the target user DN
is CN=Jane Doe,CN=users,CN=microsoft,CN=com and the SAM account name
attribute is "janed," the -hmdir parameter can have
the following substitution:

-hmdir \users\$username$\home

The value of the -hmdir parameter is modified to the following value:

- hmdir \users\janed\home
