Is pg_ident.conf working?

When i'm trying to run psql, is says:

psql --version
psql (PostgreSQL) 9.3.12
psql
psql: FATAL:  Peer authentication failed for user "testuser"

Here is my pg_hba.conf:

# Database administrative login by Unix domain socket
local   all             postgres                                peer

# TYPE  DATABASE        USER            ADDRESS                 METHOD

# "local" is for Unix domain socket coections only
local   all             all                                     peer    map=testmap
# IPv4 local coections:
host    all             all             127.0.0.1/32            md5
# IPv6 local coections:
host    all             all             ::1/128                 md5

Here is my pg_ident.conf:

# MAPNAME       SYSTEM-USERNAME         PG-USERNAME
testmap         testuser                postgres

And postgresql.conf:

data_directory = '/var/lib/postgresql/9.3/main'
hba_file = '/etc/postgresql/9.3/main/pg_hba.conf'
ident_file = '/etc/postgresql/9.3/main/pg_ident.conf'
exteal_pid_file = '/var/run/postgresql/9.3-main.pid'
listen_addresses = '*'
port = 5432
max_coections = 100
unix_socket_directories = '/var/run/postgresql'
ssl = true
ssl_cert_file = '/etc/ssl/certs/ssl-cert-snakeoil.pem'
ssl_key_file = '/etc/ssl/private/ssl-cert-snakeoil.key'
shared_buffers = 128MB
log_line_prefix = '%t '
log_timezone = 'UTC'
datestyle = 'iso, mdy'
timezone = 'UTC'
lc_messages = 'C'
lc_monetary = 'C'
lc_numeric = 'C'
lc_time = 'C'
default_text_search_config = 'pg_catalog.english'

PostgreSQL Version: 9.3.12

What i'm doing wrong?
