It means anyone who has successfully authenticated, by any means.

No. Such a restriction would prevent distributed authentication from ever
The downside of not being able to be able to specify authenticated DNs vs
DNs that actually map to an entry in the database is that for some things
(like SASL/GSSAPI setups) it makes the "users" value completely worthless,
as any kerberos principal in the KDB that connects to the ldap servers is
considered a "user". Thus I had to rework all my acls to avoid ever using
the "users" concept when it would have been quite useful (and had to resort
to sets instead).
