hba_conf: only first line is checked

Hi all,

My probleme is the following:
I want to allow some user to connect to my db with password authentication against
a first password file and allow other user against  a second one. I ve writen  the following pg_hba.conf:

host           all   192.168.1.201   255.255.255.255       password passwd
host           all   192.168.1.201   255.255.255.255       password passwd2

the Problem is if the user is present in the second password file, he is always rejected.
(If i comment the first line in the hba.conf, it works)

Is anyone have a solution?

Tanks a lot
