It is likely you have problem with pool_hba.conf.
Have you seen this kind of message in your log file right after pgpool
starting up?
2012-08-31 10:48:27 DEBUG: pid 5274: loading "/home/t-ishii/work/git.postgresql.org/test/etc/pool_hba.conf" for client authentication configuration file
If yes, I would like to see whole pool_hba.conf.
