# Example Postgres95 host access control file.
|
|
|
|
#
|
|
|
|
#
|
|
|
|
# This file controls what hosts are allowed to connect to what databases
|
|
|
|
# and specifies some options on how users on a particular host are identified.
|
|
|
|
#
|
|
|
|
# Each line (terminated by a newline character) is a record. A record cannot
|
|
|
|
# be continued across two lines.
|
|
|
|
#
|
|
|
|
# There are 3 kinds of records:
|
|
|
|
#
|
|
|
|
# 1) comment: Starts with #.
|
|
|
|
#
|
|
|
|
# 2) empty: Contains nothing excepting spaces and tabs.
|
|
|
|
#
|
|
|
|
# 3) content: anything else.
|
|
|
|
#
|
|
|
|
# Unless specified otherwise, "record" from here on means a content
|
|
|
|
# record.
|
|
|
|
#
|
|
|
|
# A record consists of tokens separated by spaces or tabs. Spaces and
|
|
|
|
# tabs at the beginning and end of a record are ignored as are extra
|
|
|
|
# spaces and tabs between two tokens.
|
|
|
|
#
|
|
|
|
# The first token in a record is the record type. The interpretation of the
|
|
|
|
# rest of the record depends on the record type.

# host DBNAME IP_ADDRESS ADDRESS_MASK USERAUTH [MAP]
|
|
|
|
#
|
|
|
|
# DBNAME is the name of a Postgres database, or "all" to indicate all
|
|
|
|
# databases.
|
|
|
|
#
|
|
|
|
# IP_ADDRESS and ADDRESS_MASK are a standard dotted decimal IP address and
|
|
|
|
# mask to identify a set of hosts. These hosts are allowed to connect to
|
|
|
|
# Database DBNAME.
|
|
|
|
#
|
|
|
|
# USERAUTH is a keyword indicating the method used to authenticate the
|
|
|
|
# user, i.e. to determine that the principal is authorized to connect
|
|
|
|
# under the Postgres username he supplies in his connection parameters.
|
|
|
|
#
|
|
|
|
# ident: Authentication is done by the ident server on the remote
|
|
|
|
# host, via the ident (RFC 1413) protocol.
|
|
|
|
#
|
|
|
|
# trust: No authentication is done. Trust that the user has the
|
|
|
|
# authority to user whatever username he says he does.
|
|
|
|
# Before Postgres Version 6, all authentication was this way.
|
|
|
|
#
|
|
|
|
# MAP is the name of a map that matches an authenticated principal with
|
|
|
|
# a Postgres username. If USERNAME is "trust", this value is ignored and
|
|
|
|
# may be absent.
|
|
|
|
#
|
|
|
|
# In the case of USERAUTH=ident, this is a map name to be found in the
|
|
|
|
# pg_ident.conf file. That table maps from ident usernames to Postgres
|
|
|
|
# usernames. The special map name "sameuser" indicates an implied map
|
|
|
|
# (not found in pg_ident.conf) that maps every ident username to the identical
|
|
|
|
# Postgres username.
