[Pgpool-general] Problem PGPOOL-II (1.3) with password

[SERY Daniel]

Hi,

I'm working for a french company and we are installing PGPOOL-II (release
1.3 with HA) and 2 backends (postgresql 8.2.4/Debian Etch).
The goal is to have load-balancing and replication between the backends (2
and soon 3).
PGPOOL-II is installed on 2 servers with heartbeat, pgpooladmin and the psql
client 8.2.4 (in fact, we have libpq4 and 5 because apache2 needs libpq4,
but we have libpq5-dev and pgpool was compiled with this version).
All is works great but an authentication problem.

In the backend's pg_hba.conf, we had put "trust" and all is works.
Now, we try to put password and we have this message : 

"psql: server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request."

In debug, we have :
"2007-11-14 17:16:12 DEBUG: pid 23054: trying clear text password

We see the message "failed to read password packet "p" and after this, I
type the password and I have the first message.

Do you have an idea of this problem ?

Thanks for advance,

Regards
Daniel.
