Huh?
16 bits => 65536 users (Current)
32 bits => 4,294,967,296 users (including 0 and -1)
4 Billion user id's is not enough?
(Putting on my Samba Development Team hat now)... One possible
reason for going to 64 bit uid_t and gid_t would be to aid mapping Windows
global ids to Unix uids and gids. The Windows IDs include information about
the domain they're a part of. Windows IDs are also used for groups,
users (a group ID is just another user ID - which is not a bad idea),
and machines. Mapping them is a major pain. That would be important
for ntfs as well as samba.
