# The default 0666 mode allows anyone to connect to the socket, but the
# userdb lookups will succeed only if the userdb returns an "uid" field
that
# matches the caller process's UID. Also if caller's uid or gid matches
the
# socket's uid or gid the lookup succeeds. Anything else causes a failure.
