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:
|
|

|
|
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.
