Thank you to those that replied - I was able to make a working program. Here is the working snippet (thank you meetraz):

   my $oContainer = Win32::OLE->GetObject("LDAP://OU=$ou, DC=nmh, DC=n
+mhschool, DC=ORG");
   my $oUser = $oContainer->MoveHere("LDAP://CN=$logon, cn=Users, DC=n
+mh, DC=nmhschool, DC=ORG","CN=$logon");
   $oUser->SetInfo();
[download]

(where $ou is the destination OU and $logon is the user's logon name)

The point I have traditionally missed is that the default OU of 'Users' must be specified as 'CN=Users' not 'OU=Users'.

Others have asked for my examples and general account creation in AD, so I will post my entire script in the Code Catacombs.

Thanks again,
John
