# PostgreSQL Client Authentication Configuration File
|
|
||||||
# ===================================================
|
|
||||||
#
|
|
||||||
# Refer to the PostgreSQL Administrator's Guide, chapter "Client
|
|
||||||
# Authentication" for a complete description. A short synopsis
|
|
||||||
# follows.
|
|
||||||
#
|
|
||||||
# This file controls: which hosts are allowed to connect, how clients
|
|
||||||
# are authenticated, which PostgreSQL user names they can use, which
|
|
||||||
# databases they can access. Records take one of these forms:
|
|
||||||
#
|
|
||||||
# local DATABASE USER METHOD [OPTION]
|
|
||||||
# host DATABASE USER CIDR-ADDRESS METHOD [OPTION]
|
|
||||||
# hostssl DATABASE USER CIDR-ADDRESS METHOD [OPTION]
|
|
||||||
# hostnossl DATABASE USER CIDR-ADDRESS METHOD [OPTION]
|
|
||||||
#
|
|
||||||
# (The uppercase items must be replaced by actual values.)
|
|
||||||
#
|
|
||||||
# The first field is the connection type: "local" is a Unix-domain socket,
|
|
||||||
# "host" is either a plain or SSL-encrypted TCP/IP socket, "hostssl" is an
|
|
||||||
# SSL-encrypted TCP/IP socket, and "hostnossl" is a plain TCP/IP socket.
|
|
||||||
#
|
|
||||||
# DATABASE can be "all", "sameuser", "samerole", a database name, or
|
|
||||||
# a comma-separated list thereof.
|
|
||||||
#
|
|
||||||
# USER can be "all", a user name, a group name prefixed with "+", or
|
|
||||||
# a comma-separated list thereof. In both the DATABASE and USER fields
|
|
||||||
# you can also write a file name prefixed with "@" to include names from
|
|
||||||
# a separate file.
|
|
||||||
#
|
|
||||||
# CIDR-ADDRESS specifies the set of hosts the record matches.
|
|
||||||
# It is made up of an IP address and a CIDR mask that is an integer
|
|
||||||
# (between 0 and 32 (IPv4) or 128 (IPv6) inclusive) that specifies
|
|
||||||
# the number of significant bits in the mask. Alternatively, you can write
|
|
||||||
# an IP address and netmask in separate columns to specify the set of hosts.
|
|
||||||
#
|
|
||||||
# METHOD can be "trust", "reject", "md5", "crypt", "password",
|
|
||||||
# "krb5", "ident", or "pam". Note that "password" sends passwords
|
|
||||||
# in clear text; "md5" is preferred since it sends encrypted passwords.
|
|
||||||
#
|
|
||||||
# OPTION is the ident map or the name of the PAM service, depending on METHOD.
|
|
||||||
#
|
|
||||||
# Database and user names containing spaces, commas, quotes and other special
|
|
||||||
# characters must be quoted. Quoting one of the keywords "all", "sameuser" or
|
|
||||||
# "samerole" makes the name lose its special character, and just match a
|
|
||||||
# database or username with that name.
|
|
||||||
#
|
|
||||||
# This file is read on server startup and when the postmaster receives
|
|
||||||
# a SIGHUP signal. If you edit the file on a running system, you have
|
|
||||||
# to SIGHUP the postmaster for the changes to take effect. You can use
|
|
||||||
# "pg_ctl reload" to do that.
|
|
||||||
|
|
||||||
# Put your actual configuration here
|
|
||||||
# ----------------------------------
|
|
||||||
#
|
|
||||||
# If you want to allow non-local connections, you need to add more
|
|
||||||
# "host" records. In that case you will also need to make PostgreSQL listen
|
|
||||||
# on a non-local interface via the listen_addresses configuration parameter,
|
|
||||||
# or via the -i or -h command line switches.
