problems in connecting to a server - Mailing list pgadmin-support

Hi

I have two Debian systems, both with

psql (PostgreSQL) 7.4.2
pgadmin3 1.0.2

but in one of them (the laptop) I am unable to make a connection with 
pgadmin3, I always get:

----------
2004-05-11 10:13:12 ERROR  : Error connecting to the server: FATAL:  IDENT 
authentication failed for user "pedro"
----------

The "pedro" user has been created previously with the "createuser"  command

----------
pedro@pcporta16:~$ psql template1
