probable pg_hba.conf configuration issues

Hi,

I'm sorry if this question have been asked earlier, but i could not find
any valid result through googling.

I'm running postgresql 9.1 on Windows 7 (64 bit) and i've following
configuration in pg_hba.conf.

host all superuser1 127.0.0.1/32 password
host all normaluser1 127.0.0.1/32 password

Using command line : psql -U superuser1 & psql -U normaluser1 asks for
password and login successfully. - perfect. (We are only alloing local
connections, remote connections to database are disabled)

But if I try to connect using pgadmin (from the same machine) it gives
acess to database without password, i'm surprised as it does not seem to
respect pg_hba.conf or i'm terribly wrong in the configuration somewhere.

Does somebody have any idea what is wrong?

Thank you

Ravi.
