Hi Hon-Kie, 

Thinking some more about this ..... 

This type of behavior is expected if you have a course for which the last 
access date for students has been set to be before the last enrollment date. 
Each time it runs Autoenroll.pl checks the auto-enrollment window, and if 
the current date falls between start and end enrollment dates it will 
proceed with adds and/or drops for the course.  It will report successful 
enrollment for any students which it adds; students to be added are those 
that appear in the institutional list but who are not "Active" or "Future" 
students (according to the LON-CAPA classlist).  So if the last access date 
has already passed it will add all the registered students (because they are 
neither active nor future students) each time it runs.  The solution is 
simply to change the last auto-enrollment date or the default last access 
date for students in the course, so that the last auto-enrollment date does 
not occur after the last access date.
