# PostgreSQL HOST-BASED ACCESS (HBA) CONTROL FILE
|
|
#
|
|
#
|
|
# This file controls:
|
|
#
|
|
# o which hosts are allowed to connect
|
|
# o how users are authenticated on each host
|
|
# o databases accessible by each host
|
|
#
|
|
# It is read on postmaster startup and when the postmaster receives a SIGHUP.
|
|
# If you edit the file on a running system, you have to SIGHUP the postmaster
|
|
# for the changes to take effect.

|
|
# Each line is a new record. Records cannot be continued across multiple
|
|
# lines. Comments begin with # and continue to the end of the line.
|
|
# Blank lines are ignored. A record consists of tokens separated by
|
|
# multiple spaces or tabs.
|
|
#
|
|
# The first token of a record indicates its type. The remainder of the
|
|
# record is interpreted based on its type.

|
|
# Record Types
|
|
# ============
|
|
#
|
|
# There are three types of records:
|
|
#
|
|
# o host
|
|
# o hostssl
|
|
# o local
|
|
#
|
|
# host
|
|
# ----
|
|
#
|
|
# This record identifies the networked hosts that are permitted to connect
|
|
# via IP connections.
|
|
#
|
|
# Format:
|
|
#
|
|
# host DBNAME IP_ADDRESS ADDRESS_MASK AUTH_TYPE [AUTH_ARGUMENT]
|
|
#
|
|
# DBNAME can be:
|
|
#
|
|
# o the name of a PostgreSQL database
|
|
# o "all" to indicate all databases
|
|
# o "sameuser" to allow access only to databases with the same
|
|
# name as the connecting user
|
|
#
|
|
# IP_ADDRESS and ADDRESS_MASK are standard dotted decimal IP address and
|
|
# mask values. IP addresses can only be specified numerically, not as
|
|
# domain or host names.
|
|
#
|
|
# AUTH_TYPE and AUTH_ARGUMENT are described below.
|
|
#
|
|
# There can be multiple "host" records, possibly with overlapping sets of
|
|
# host addresses. The postmaster finds the first entry that matches the
|
|
# connecting host IP address and the requested database name. If no entry
|
|
# matches the database/hostname combination, the connection is rejected.
|
|
#
|
|
#
|
|
# hostssl
|
|
# -------
|
|
#
|
|
# The format of this record is identical to "host".
|
|
#
|
|
# This record identifies a set of network hosts that are permitted to
|
|
# connect to databases over secure SSL IP connections. Note that a "host"
|
|
# record will also allow SSL connections. "hostssl" forces these
|
|
# hosts to use *only* SSL-secured connections.
|
|
#
|
|
# This keyword is only available if the server was compiled with SSL
|
|
# support enabled.
|
|
#
|
|
#
|
|
# local
|
|
# -----
|
|
#
|
|
# This record identifies the authentication to use when connecting to
|
|
# the server via a local UNIX domain socket. UNIX-socket connections are
|
|
# allowed only if this record type appears.
|
|
#
|
|
# Format:
|
|
#
|
|
# local DBNAME AUTH_TYPE [AUTH_ARGUMENT]
|
|
#
|
|
# This format is identical to the "host" record type except the IP_ADDRESS
|
|
# and ADDRESS_MASK fields are omitted.
|
|
#
|
|
# As with "host" records, the first "local" record matching the requested
|
|
# database name is used.
|
|
#
|
|
#
|
|
#
|
|
# Authentication Types (AUTH_TYPE)
|
|
# ================================
|
|
#
|
|
# AUTH_TYPE indicates the method used to authenticate users. The username
|
|
# is specified in the connection request. A different AUTH_TYPE can be
|
|
# specified for each record in the file.
|
|
#
|
|
# trust: No authentication is done. Any valid username is accepted,
|
|
# including the PostgreSQL superuser. This option should
|
|
# be use only for machines where all users are truested.
|
|
#
|
|
# password: Authentication is done by matching a password supplied
|
|
# in clear by the host. If no AUTH_ARGUMENT is used, the
|
|
# password is compared with the user's entry in the
|
|
# pg_shadow table.
|
|
#
|
|
# If AUTH_ARGUMENT is specified, the username is looked up
|
|
# in that file in the $PGDATA directory. If the username
|
|
# exists but there is no password, the password is looked
|
|
# up in pg_shadow. If a password exists in the file, it is
|
|
# it used instead. These secondary files allow fine-grained
|
|
# control over who can access which databases and whether
|
|
# a non-default passwords are required. The same file can be
|
|
# used in multiple records for easier administration.
|
|
# Password files can be maintained with the pg_passwd(1)
|
|
# utility. Remember, these passwords override pg_shadow
|
|
# passwords.
|
|
#
|
|
# crypt: Same as "password", but authentication is done by
|
|
# encrypting the password sent over the network. This is
|
|
# always preferable to "password" except for old clients
|
|
# that don't support "crypt". Also, crypt can use
|
|
# usernames stored in secondary password files but not
|
|
# secondary passwords.
|
|
#
|
|
# ident: Authentication is done by the ident server on the local
|
|
# (127.0.0.1) or remote host. AUTH_ARGUMENT is required and
|
|
# maps names found in the $PGDATA/pg_ident.conf file. The
|
|
# connection is accepted if the file contains an entry for
|
|
# this map name with the ident-supplied username and the
|
|
# requested PostgreSQL username. The special map name
|
|
# "sameuser" indicates an implied map (not in pg_ident.conf)
|
|
# that maps each ident username to the identical PostgreSQL
|
|
# username.
|
|
#
|
|
# krb4: Kerberos V4 authentication is used.
|
|
#
|
|
# krb5: Kerberos V5 authentication is used.
|
|
#
|
|
# reject: Reject the connection. This is used to reject certain hosts
|
|
# that are part of a network specified later in the file.
|
|
# To be effective, "reject" must appear before the later
|
|
# entries.
|
|
#
|
|
# Local UNIX-domain socket connections support only the AUTH_TYPEs of
|
|
# "trust", "password", "crypt", and "reject".
|
|
#
|
|
#
|
|
#
|
|
# Examples
|
|
# ========
|
|
#
|
|
#
|
|
# Allow any user on the local system to connect to any database under any
|
|
# username using Unix-domain sockets (the default for local connections):
|
|
# TYPE DATABASE IP_ADDRESS MASK AUTH_TYPE AUTH_ARGUMENT
|
|
# local all trust
|
|
#
|
|
# The same using IP connections on the same machine:
|
|
# TYPE DATABASE IP_ADDRESS MASK AUTH_TYPE AUTH_ARGUMENT
|
|
# host all 127.0.0.1 255.255.255.255 trust
|
|
#
|
|
# Allow any user from any host with IP address 192.168.93.x to
|
|
# connect to database "template1" as the same username that ident reports
|
|
# for the connection (typically his Unix username):
|
|
#
|
|
# TYPE DATABASE IP_ADDRESS MASK AUTH_TYPE AUTH_ARGUMENT
|
|
# host template1 192.168.93.0 255.255.255.0 ident sameuser
|
|
#
|
|
# Allow a user from host 192.168.12.10 to connect to database "template1"
|
|
# if the user's password in pg_shadow is correctly supplied:
|
|
#
|
|
# TYPE DATABASE IP_ADDRESS MASK AUTH_TYPE AUTH_ARGUMENT
|
|
# host template1 192.168.12.10 255.255.255.255 crypt
|
|
#
|
|
# In the absence of preceding "host" lines, these two lines will reject
|
|
# all connection from 192.168.54.1 (since that entry will be matched
|
|
# first), but allow Kerberos V5-validated connections from anywhere else
|
|
# on the Internet. The zero mask means that no bits of the host IP address
|
|
# are considered, so it matches any host:
|
|
#
|
|
#
|
|
# TYPE DATABASE IP_ADDRESS MASK AUTH_TYPE AUTH_ARGUMENT
|
|
# host all 192.168.54.1 255.255.255.255 reject
|
|
# host all 0.0.0.0 0.0.0.0 krb5
|
|
#
|
|
# Allow users from 192.168.x.x hosts to connect to any database if they
|
|
# pass the ident check. For example, if ident says the user is "james" and
|
|
# he requests to connect as PostgreSQL user "guest", the connection is
|
|
# allowed if there is an entry in $PGDATA/pg_ident.conf with map name
|
|
# "phoenix" that says "james" is allowed to connect as "guest":
|
|
#
|
|
# TYPE DATABASE IP_ADDRESS MASK AUTH_TYPE AUTH_ARGUMENT
|
|
# host all 192.168.0.0 255.255.0.0 ident phoenix
|
|
#
|
|
# See $PGDATA/pg_ident.conf for more information on Ident maps.
|
|
#
|
|
# Put your actual configuration here
|
|
# ==================================
|
|
#
|
|
# This default configuration allows any local user to connect with any
|
|
# PostgreSQL username, over either UNIX domain sockets or IP:
|
|
#
|
|
# If you want to allow non-local connections, you will need to add more
|
|
# "host" records. Also, remember IP connections are only enabled if you
|
|
# start the postmaster with the -i option.
|
|
#
|
|
# CAUTION: if you are on a multiple-user machine, the default
|
|
# configuration is probably too liberal for you. Change it to use
|
|
# something other than "trust" authentication.
|
|
#
|
|
# TYPE DATABASE IP_ADDRESS MASK AUTH_TYPE AUTH_ARGUMENT
