Hi, this has worked for me, using commas......
Do you have any other commas in the path that are *not* before the OU= or DC= parts? Maybe if an OU name contains a comma then you need to escape it.
If you have, say an OU called Accounting, Main Office then maybe you need to specify Accounting/, Main Office or Accounting\, Main Office
I can't remember which way the escape character goes.....
Regards,
Rob.
