Btw., it would be a good idea to get rid of calls to getpwent/getgrent
in future.  They *probably* won't do anymore what they were supposed to
do if you don't have passwd/group files.  A full implementation would
require to enumerate the local SAM and, at least, the primary domain
accounts at runtime.  That would be possible, but it comes at a hefty
price in terms of performance.
