The Disable Old Profile command optionally disables user profiles that have not
been signed onto recently or not at all. Two retention periods may be specified
for: 1) Profiles that have not signed on recently. 2) Profiles that have never
signed on. Profiles created by the system or are PASSWORD(*NONE) are not
considered. DSAOLDPRF may be used to minimize the exposure that profiles will
be inappropriately used.
