Subject: [HACKERS] auth.c for kerberos.
I made pgsql with eBones(international version of Kerberos4). The
following modification was needed. And I added read permition for
group to srvtab instead of running postmaster as root.
Subject: [HACKERS] password authentication
This patch adds support for plaintext password authentication. To use
it, you add a line like
host all 0.0.0.0 0.0.0.0 password pg_pwd.conf
to your pg_hba.conf, where 'pg_pwd.conf' is the name of a file containing
the usernames and password hashes in the format of the first two fields
of a Unix /etc/passwd file. (Of course, you can use a specific database
name or IP instead.)
Then, to connect with a password through libpq, you use the PQconnectdb()
function, specifying the "password=" tag in the connect string and also
adding the tag "authtype=password".
I also added a command-line switch '-u' to psql that tells it to prompt
for a username and password and use password authentication.
directory. The code that looks for the pg_hba file doesn't use it, though,
so the postmaster uses the wrong pg_hba file. Also, when the postmaster
looks in one directory and the user thinks it is looking in another
directory, the error messages don't give enough information to solve the
problem. I extended the error message for this.
