Because, when you have all of your users in one place, many other
things work better. For example, with the proper mailer flags,
sendmail will recognize all of them as local users.

PAM is extremely flexible. The best place in pam.conf to authorize
users for different services is the Account management section. In a
simple case, you only need a PAM module that consults a table of user
names or group names. Typically on an e-mail server, you'd want to
authorize all users to read e-mail but only a few to log in to the
server. So, you'd set up the PAM service names that Cyrus uses
(cyrus, imap, pop, sieve) with no restriction in pam.conf, but the
default service name (other) would invoke your new PAM module to
restrict access. On a different machine, say to provide shell access
for all users, you'd set up a different PAM configuration.
