The Error: 603 No such attribute is returned when the attribute is present

Error -603 is returned when searching for a specific attribute on an object. This attribute is present and can be seen via dsbrowse, iMonitor, etc.

Checked to see if the user had rights to the attribute. Found that the user did not have rights to the attribute. Shouldn't the error -672 have been returned?

The error code -603 is returned if the user doesn't have access to the
attribute present. This is the same behavior as in 873. This is because we
don't want the user, not having access, to know if an attribute is present or
not.
