Authentication
Why Authenticate?
- Users authenticate so that Jake knows from whose quota the
printed pages should be deducted. Jake asks the printer before
and after the job is printed how many pages it has printed in
its lifetime and then deducts the difference between the two
from the user's quota.
Unix Passwords
- Jake uses Unix passwords and userids to authenticate users.
Kerberos Passwords
- It's possible to not only use Unix passwords and userids. At
Columbia we also use our Kerberos ids to authenticate users.
