Login Failures After Upgrade

Folks,

Just upgraded from 7.1.3 to 7.3 (using RPMs) and now none of the assigned
users can login as before. Tried resetting passwords with 'ALTER USER XXX
WITH PASSWORD='pwd' and it didn't help. pg_hba.conf listing follows:


# TYPE  DATABASE    USER        IP-ADDRESS        IP-MASK           METHOD

local   all        all
password
host    all        all     127.0.0.1       255.255.255.255 password
host    all        all     192.168.1.0     255.255.255.0   password
host    all        all     24.128.216.179  255.255.255.255 password
host    all        all     217.33.127.174   255.255.255.248 password

Had to set the first two lines to 'trust' to get apache/php to access data.
Would like to have password protection working again, but can't figure out
what's gone wrong. Any ideas appreciated, thanks.

Rgds,
