The following configuration line should allow anyone
to login as him/herself or guest.
host all 127.0.0.1 255.255.255.255 password
I don't think this would weaken your current level of
security, as a user name and password would still be
needed to login as someone else. You could even
assign passwords that are different from users' system
passwords.
Best of luck,
