Summary0000123: MD5 authentication is not requiring password.
DescriptionMD5 authentication is not requiring password. It checks the user in pool_password file, but accepts null passwords and wrong passwords.

Two servers PostgreSQL 9.1 and pgpool-II 3.4.0, running as MASTER/SLAVE mode and streaming replication. See configuration files attached.

It was tested with pgpool-II 3.2.5 and 3.3.3, same problem occurs.

I've been reviewing the configuration files and seems to be all right. I don't know if I'm missing something.

Steps To ReproduceCreate a user/password in PostgreSQL.

Update pool_passwd file using pg_md5 and specifying the same user/password created in PostgreSQL.

Add entries in pool_hba.conf and pg_hba.conf of md5 type.

Reload PostgreSQL and pgpool.

Try to connect using pgpool port, informing user without password. It works for me.
TagsNo tags attached.

Which IP is pgpool running on? It should match with the one specified in pg_hba.conf.

Sorry, I'm using two servers, both running PostgreSQL and Pgpool.

Pgpool is running in the same servers of PostgreSQL, IPs and

HBA files are equal in both servers.

Followings in pg_hba.conf allow pgpool to access PostgreSQL without password.

host all all trust
host all all trust

Problem solved, pg_hba.conf was changed on both servers with the following entries for pgpool:
host all all md5
host all all md5

Sorry about spending your time, I'm new with Pgpool and PostgreSQL.

Thanks for agility in responding!
