trouble with pgaccess

                Hi everybody !

        Excuse my poor english, since I'm french, and the dummy question I will
ask, since I'm new using pgaccess and postgresql.
        I have successfully installed pgaccess, but when I try to connect to
the databses I have created, I get the message :

        Error trying to connect to database 'garde' on host
        PostgreSQL error message : Connection to database failed
        FATAL : IDENT authentication failed for user "philippe"

        User philippe has been created by superuser postgres and is granted for
this database.
        Can anybody help me ?

        Thanks
