nooby install login security problem

I have loaded postresql 8.4 on my Windows xp computer from a zip file

(not using one-click install).

i start the system , it says "database ready to accept connections"

I try  to log in through   phpPgAdmin (4.2.2) my problem is it won't let me log in under any name i try, password or no password because of "security reasons"

config.php file i set this:

$conf['extra_login_security'] = false;

i did use the name "postgres" during installation, for the name of the "limited account" i created as in instructions. 

my pg_hba.conf file looks like this:

# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD

# IPv4 local connections:

local    all         all                              trust

host    all         all         127.0.0.1/32          trust

# IPv6 local connections:

#host    all         all         ::1/128               trust

I have not changed the pg_ident.conf file.

tnx, brian
