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.
