[pgpool-general: 1485] pgpool and md5 auth

[uruvela of india]

Hi,

I'm looking for some help with MD5 authentification in pgpool.

1st :

pgpool-II version 3.2.2 (namameboshi)
PG 9.2.3

* On PG server : I create a toto role with encrypted password, and add this line in pg_hba.conf :
host mydb toto my_pgpool_ip/32 md5

Restarting PG.


* On pgpool server :

pgpool.conf :

enable_pool_hba = on 
pool_passwd = 'pool_passwd'

Create toto md5 password in pool_passwd :

toto:md5cb926329843e9a8f3eb15e0a2a5c9851

Checking same thing in PG in pg_authid :

| toto | md5cb926329843e9a8f3eb15e0a2a5c9851 |

pool_hba.conf :

add this line : local mydb toto md5

2nd :

Starting pgpool.

Using perl script dbi.pl http://dbi.pl&lang=en  to test on pgpool server :

use DBI;
$DB_name = 'mydb';
$DB_user = 'toto';
$DB_pwd = 'mypassword';
$dbh = DBI->connect("dbi:Pg:dbname=$DB_name","$DB_user","$DB_pwd");
if ( !defined $dbh ) { die "Cannot connect to database!\n"; }
$sth = $dbh->prepare("SELECT * FROM pg_user");
$sth->execute();
while ( ($id,$name) = $sth->fetchrow_array() ) { print "$id\t\t $name \n";
}
$sth->finish();
$dbh->disconnect();


1st launch : working

2nd launch : changing md5 to reject in pool_hba.conf (restarting pgpool) : DBI connect('dbname=mydb','toto',...) failed: ERROR: no pool_hba.conf entry for host "[local]", user "toto", database "mydb" at dbi.pl http://dbi.pl&lang=en  line 5

3rd launch : back to md5 in pool_hba.conf and changing toto by tito in pool_passwd (restarting pgpool) : DBI connect('dbname=mydb','toto',...) failed: ERROR: "MD5" authentication with pgpool failed for user "toto" at dbi.pl http://dbi.pl&lang=en  line 5

4th launch : back to toto vs tito in pool_passwd and deleted everything after md5 (now pool_passwd is like this 'toto:md5') + restarting pgpool : working.


I miss something i'm sure :) but why it's working in 4th try ? It's seems only PG server do it's authentification job's.
