Correct. The user will see each file backed up after his id was added to
the passwd.

I had opened a Record for this (PMR 6012X). After many discussions with
IBM support I agreed to close the record. I guess we should consider the
bug as a feature.

Funny enough. As I have 16,000 users I had asked the same question. The
answer was that I should write a script to add the access entries. IBM
didn't know exactly what will happen if I do so. They told me that I
should expect at least loss of performance.

BTW: Assumed that I will get trouble with that many entries, have you an
idea how to get rid of 16,000 SET ACC entries with DEL ACC which
provides you with a complete list of all entries?
