There are a lot of unix tools to ask networks to query that information and they'll happily do it for other unix systems they connect to. When I was in college in the last 90s, I'd often lookup phone numbers and such of students at other universities using command line unix utilities.

AFAIK that can expose the username, none of the other fields, but is typically set to an alternate identifier. Or do you mean shared mainframes with many users on the same system? That'd still be local to the system, you just happened to have access to that system. Are you sure you're not just thinking of ldap/directory lookups?
