FATAL 1: Password authentication failed

I have tested some java code to connect to PostgreSQL database using 'trust' relationship, which works.

Quote:

[snathan@sip008 security]$ java Sample
DAtabase :PostGRESQL
Inside Main of Sample ####
Here
Database Driver

rg.postgresql.Driver
Database Datasource :jdbc

ostgresql://192.168.66.3:5432/test
Database Login :u_test
Database Password :u_test

However, when I change the pg_hba.conf to have 'password' or 'md5' or 'crypt', the connection fails with the above error. I am able to connect using 'psql' ...

Something unusual has occured to cause the driver to fail. Please report this exception: Exception: java.sql.SQLException: FATAL 1: Password authentication failed for user "u_test"

Solution

Sorry for my English. I am Spanish.

When you change the METHOD in pg_hba.conf file, the password of users ares invalid with PASSWORD, CRYPT, MD5, ... methods.
After change pg_hba.conf, from localhost execute psql and do:
ALTER USER (username) WITH ENCRYPTED PASSWORD '(the password)'

And, PostGreSQL is all right.
Many people wrote about pg_hba.conf file, but they don't written about update all users passwords after do it.

It's work for psql client and jdbc.
