-The pathces and a prototype tool to manipulate the ``flat password file
-'' functionality of PostgreSQL6.1
-1. File
-Makefile
-pg_passwd.c the source file of the tool.
-2. How to specify pasword files and their format.
-Specify the password file in the same style of Ident authentication in
-$PGDATA/pg_hba.conf
-host unv 133.65.96.250 255.255.255.255 password passwd
-The above line allows access from 133.65.96.250 using the passwords listed
-in $PGDATA/passwd.
-The format of the password files follows those of /etc/passwd and
-/etc/shadow: the first field is the user name, and the second field
-is the encrypted password. The rest is completely ignored. Thus
-the following three sample lines specify the same user and password pair:.
-pg_guest:/nB7.w5Auq.BY:10031::::::
-pg_guest:/nB7.w5Auq.BY:93001:930::/home/guest:/bin/tcsh
-pg_guest:/nB7.w5Auq.BY:93001
-Note that the original src/backend/libpq/password.c has a bug, which
-disallows the first and the second format. If you want to use these
-formats, please make sure you've applied the patch accompanied with
-this tool.
-3. Usage of pg_passwd
-Supply the password file to the pg_passwd command. In the case described
-above, after ``cd'ing to $PGDATA, the following command execution specify
-the new password for pg_guest:
-% pg_passwd passwd
-Username: pg_guest
-Password:
-Re-enter password:
-where the Password: and Re-enter password: prompts require the same
-password input which are not displayed on the terminal.
-The original password file is renamed to ``passwd.bk''.
-4. How to specify pasasword authentication
-You can use the password authentication fro psq, perl, or pg{tcl,tk}sh.
-4.1 psql
-Use the -u option. Note that the original distribution includes a bug.
-Please make sure you've applied the patch distributed with this tool.
-The following lines show the sample usage of the option:
-% psql -h hyalos -u unv
-Username: pg_guest
-Password:
-Welcome to the POSTGRESQL interactive sql monitor:
- Please read the file COPYRIGHT for copyright terms of POSTGRESQL
- type \? for help on slash commands
- type \q to quit
- type \g or terminate with semicolon to execute query
- You are currently connected to the database: unv
-unv=>
-4.2 perl5
-Use the new style of the Pg.pm like this
-$conn = Pg::connectdb("host=hyalos authtype=password dbname=unv
- user=pg_guest password=xxxxxxx");
-For more details, the users refer to to ``src/pgsql_perl5/Pg.pm''.
-4.3 pg{tcl,tk}sh
-Use the pg_connect comamnd with -conninfo option thus
-% set conn [pg_connect -conninfo \
- "host=hyalos authtype=password dbname=unv \
- user=pg_guest password=xxxxxxx "]
-Use can list all of the keys for the option by executing the following
-command:
-% puts [ pg_conndefaults]
-5. Acknowledgment
-Mr. Ishii, SRA, pointed out the original bugs in the tool. He also
-supplied the Makefile for this distribution.
