We routinely see systems with upwards of 100,000 users. How they get there -- NIS, NIS+, LDAP, DCE, AFS, whatever -- varies widely. I'm sure that Linux will wind up (eventually) in the same situation. Please keep in mind that the purpose of having =reserved= UID/GID values is for system users/groups. I've never seen a system with more than a dozen or so admins and several dozen application or service specific reserved UID values. As a thought, someone might want to create a "Linux Reserved Number Registry" so that vendors can reserve UID/GID values and have some assurance that similarly concerned vendors won't expect that a specific UID/GID value will be available. -- Julie.
