Re: Authentication Question

There is no hostname specified in the PHP code when it connects to PostgreSQL, so it's using a socket connections then correct? Also, I did SIGHUP the PostgreSQL server after the configuration changes. Here's what the PHP config file looks like that's used to connect to PostgreSQL

$db = array(
"type" => "pgsql",
"host" => "",
"port" => "",
"name" => "issue-tracker",
"user" => "webuser",
"pass" => "password"
);

I wonder if it's trying to authenticate because there's a username and password specified in the pg_connect() function. However, when I remove the username and password I get the following error...

Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL: IDENT authentication failed for user "dbname=issue-tracker" . in /var/www/html/issue-tracker/includes/classes/dbi.class.php on line 98 "

Thoughts?

This is correct if you specify a host name:

pg_connect("host=local dbname=db") <- TCP/IP
pg_connect("dbname=db") <- local unix sockets (i.e. no host=)
