Postfixadmin is not working with Postgres

Question

I am new to both postgres and postfix, I decided to use to postfixadmin with Postgres to gain so hands on, I have ran through detailed steps mentioned in different websites, and I have checked another working installation of Postgres (but without postfixadmin), but whenever I accessing the setup.php for postfixadmin from http://mydomain.com:8080 I am getting:

Error: Can't connect to database
Please edit the $CONF['database_*'] parameters in config.inc.php.
DEBUG INFORMATION:
Connect: failed to connect to database.

I configured the postfixadmin to use initially postfix user, but as the postfix is created by default as no login user, so I created another user called admin and changed this in config.inc.php as well, but I am still getting the same error

Here are the user created on the system related to this stuff:

# cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
postfix:x:89:89::/var/spool/postfix:/sbin/nologin
postgres:x:26:26:PostgreSQL Server:/var/lib/pgsql:/bin/bash
admin:x:500:500::/home/admin:/bin/bash

Here am I configuring the user admin in Postgres:

# su - postgres
-bash-4.1$ template1
-bash: template1: command not found
-bash-4.1$ template1#
-bash: template1#: command not found
-bash-4.1$ psql template1
psql (8.4.18)
Type "help" for help.
template1=# CREATE USER admin WITH PASSWORD 'complexpassword';
CREATE ROLE
template1=# GRANT ALL PRIVILEGES ON DATABASE postfix to admin;
GRANT
template1=# \q
-bash-4.1$ logout

Here are the configuration of the Postgres:

-bash-4.1$ psql
psql (8.4.18)
Type "help" for help.

Here I am testing user admin:

# su - admin
$ psql -d postfix -U admin
psql (8.4.18)

postfix=> exit
postfix-> \q

Here I am testing postfix user (nologin):

# su - postfix

Here are the php packages installed:

Here are the checks showing that the Postgres is listening to posrt 5432:

#netstat -an|grep 5432
tcp        0      0 127.0.0.1:5432              0.0.0.0:*                   LISTEN
unix  2      [ ACC ]     STREAM     LISTENING     12136  /tmp/.s.PGSQL.5432


# telnet localhost 5432
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
^]
telnet> quit
Connection closed.

But What is really strange as well when I try to run the setup.php page I can see the following:

# netstat -an| grep 5432
tcp        0      0 127.0.0.1:5432              0.0.0.0:*                   LISTEN
tcp        0      0 127.0.0.1:45445             127.0.0.1:5432              TIME_WAIT
unix  2      [ ACC ]     STREAM     LISTENING     12136  /tmp/.s.PGSQL.5432

The Postgres' log contains:

LOG: could not connect to Ident server at address "127.0.0.1", port 113: Connection refused
FATAL: Ident authentication failed for user "postfix"
LOG: could not connect to Ident server at address "127.0.0.1", port 113: Connection refused
FATAL: Ident authentication failed for user "postfix"
LOG: could not connect to Ident server at address "127.0.0.1", port 113: Connection refused
FATAL: Ident authentication failed for user "postfix"
LOG: could not connect to Ident server at address "127.0.0.1", port 113: Connection refused FATAL:
Ident authentication failed for user "admin"

And the pg_hba.conf is:

local all all ident
host all all 127.0.0.1/32 ident
host all all ::1/128 ident

Can someone guide me what is wrong?

Answer 1

Find in the pg_hba.conf(this file is in the same directory as the postgresql.conf) a line starting with "host", containing "127.0.0.1/32" in it and ending with "ident" and change the "ident" to "md5". Reload/restart Postgres.
