Thread: login error - Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL: password authentication failed for user "kamik"

Hi guys,
I am trying connect to Postgres by PHP. I have this PHP code:
 

But web browser writes this error:
Warning: pg_connect(): Unable to connect to PostgreSQL server: FATAL:  password authentication failed for user "***" FATAL:  password authentication failed for user "***" in /var/www/test/index.php on line 6  Warning: pg_last_error(): No PostgreSQL link opened yet in /var/www/test/index.php on line 7 Could not connect:

Main problem is that I have bad authentication for my user. In my pg_hba.conf is this:
# Database administrative login by UNIX sockets
local   all         postgres                          ident
# TYPE  DATABASE    USER        CIDR-ADDRESS          METHOD
# "local" is for Unix domain socket connections only
local   all         all                               trust
# IPv4 local connections:
host    all         all         127.0.0.1/32          trust
host    all         all         0.0.0.0/0             md5
hostssl all         all         0.0.0.0/0             md5
hostnossl all       all         0.0.0.0/0             md5
# IPv6 local connections:
host    all         all         ::1/128               md5

And in postgresql.conf I set listen_addresses = "*"

When I delete in PHP script in pg_connect host="localhost", then all works fine, because I use UNIX domain socket (I am thinging ...), but when I use "normal" connection, it is wrong. Interesting is that phppgadmin works fine ... .

So, question is what I do wrong. I thing that I have mistake in pg_hba.conf, but I am blind. I have postgresql-8.4



Best regards

J.K.

Thanks for reply, that is it. I altered user, set same password and it works!!! Why? I can not understand it. My user postgis was created by user postgres by command createuser postgis -s -d -P -E and then I typed the same pwd like now. I still do not know where was problem. Any ideas? I know that it is not much important now, but for better understanding PostgreSQL it is good to know.


Best regards

Jaromir,

I'm a novice myself so apologies if I'm of no help but I thought I'd try.

I've just tested your pg_hba.conf with a test database.  I hit problems too where the user was not set up with a password but the UNIX login would obviously still let it login.

If you're willing to give something else a go, can you use a working method to connect to the database and issue the following -

ALTER USER <user> encrypted password '<password>';

Then reattempt the localhost connection string.

Hope you don't mind another novice offering you advice but sometimes it just needs a second pair of eyes!

quick answer:
YES

phppgadmin works, pgAdmin III works, PHP framework CodeIgniter works when i set this $db['default']['hostname'] = ""; but when I set localhost, there is problem.

Just a quick obvious check - can you ping localhost?
