# PostgreSQL Client Authentication Configuration File # =================================================== # # Refer to the "Client Authentication" section in the # PostgreSQL documentation for a complete description # of this file. 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", "gss", "sspi", # "krb5", "ident", "pam" or "ldap". 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. # # CAUTION: Configuring the system for local "trust" authentication allows # any local user to connect as any PostgreSQL user, including the database # superuser. If you do not trust all your local users, use another # authentication method. # TYPE DATABASE USER CIDR-ADDRESS METHOD local all postgres ident sameuser local all all md5 host all all 127.0.0.1/32 md5 host all all 10.192.26.0/24 md5
