I am working on a script that as part of its function modifies some user attributes.  However, this gets run a few times at the beginning of a semester since people add and drop classes sometimes before the deadline prevents that.  Because of this situation, some people have no modification to be made when the API call goes out and FreeIPA throws the EmptyModlist exception.  For some reason I can't catch it with anything but catch all exception.  I need to catch it and just have the script proceed like nothing really happened if no modification is made.
