Обсуждение: Login with blank password

Is there a setting in postgresql.conf that will log the password that's used to login with?
If I add "host    all         user        172.17.32.0       255.255.255.0     password"
to pg_hba.conf the user can login with a blank password.
If I add "host    all         user        172.17.32.1       255.255.255.255     password"
to pg_hba.conf the user must enter a correct password.
This only occurs in apps I've written using libpq.
Using PostgreSQL 7.4.3 on Fedora Core 2.

Thanks

No (deliberately so).

This sounds to me like you are failing to consider the effects of the
order of entries in pg_hba.conf --- ie, in the first case the connection
is being caught by a TRUST-mode entry (or at least, not a password-based
one ... could be IDENT as well).  Don't forget to SIGHUP the postmaster
after editing pg_hba.conf, too.
