pgadmin gives me the error: no password supplied

Question

I've installed postgresql 9.2 on linux (kubuntu) and the last version of pgadmin3, but when I connect them I have this error:

An error has occurred: Error connecting to the server: fe_sendauth: no password supplied

What can I do?

I have also configured tomcat for my web application in java. In fact, postgresql was working before trying my application.

Answer 1

Change the password for role postgres:

sudo -u postgres psql postgres  alter user postgres with password 'postgres'; 

Try connect using "postgres" for both username and password.
