mod_auth_pgsql

Please somebody help me,

I'm trying to use the Apache module mod_auth_pgsql, and after entering
the user name and the password the server returns an error page (500 -
Server Internal Error).

The error that apache puts in the error_log is:
access to /var/www/html failed for 10.0.0.6, reason: PGSQL 3: ERROR:
pg_atoi: error in "diogo": can't parse "diogo"
-- Query: select senha from usuarios where codusuario='diogo'

I'm using the PostgreSQL 7.1.3 with RedHat 7.3, and Apache 1.3.23

Here is a bit of my httpd.conf:

AuthName "Atenticador do PostgreSQL"
AuthType basic

Auth_PG_host 10.0.0.7
Auth_PG_port 5432
Auth_PG_user ikono
Auth_PG_pwd *1k0n0
Auth_PG_database eyebot
Auth_PG_pwd_table usuarios
Auth_PG_uid_field codusuario
Auth_PG_pwd_field senha
Auth_PG_log_table access_log
Auth_PG_log_uname_field login
Auth_PG_log_date_field date
Auth_PG_log_uri_field request
Auth_PG_log_addrs_field ip_address
<LIMIT GET POST>
require valid-user
</LIMIT>
