How long could an Organizational or an Organizational unit object name be?

iManager is not showing this information as help option upon object creation.
eDirectory documentation is not showing this information where it is showing how to create an object using iManager.

The requiered information is available in ConsoleOne's help. You can easily verify this by clicking the help button while creating either an organization or an organizational unit object. You will see that it can be up to 64 characters long and should follow eDirectory object naming conventions.

Enhancement requests has been opened to add this information in the eDirectory documentation and in iManager help as well.
