Обсуждение: security question

Hi,

I have a quick question about my installation that puzzles me. pgsql 8.2.3 on a debian box. Tested it out the database works. pgadmin III connects fine too. I used alter table on the template1 database to give postgres user a password. I changed pg_hba to use md5 on all connections including local.

When I use psql -U postgres -d myDataBase to connect to myDataBase I do not get prompted for a password? When I su postgres and use psql myDatabase I get prompted for my password?

Is there some reason why I can login using psql to a database when postgres is supposed to use passwords for all access?

Probably a mistake I made somewhere along the line... just not sure where, usually I get my pgsql install working great!

Thanks

Dave

did you restart?

One quick point - you don't need to alter anything in the template1
database to set user's passwords.
In PgAdmin III - use the "Login roles" section to set the passwords -
that way everything will get committed correctly.

Also, have you restarted PostgreSQL since changing pg_hba.conf?

Most likely psql is picking up the password from ~/.pgpass when run as your
user.  Pgadmin3 stores passwords in .pgpass, so it's likely been put in there
by pgadmin.  As a test - move .pgpass to .pgpass.old and try to connect via
psql -U postgres -d myDataBase again.

If it didn't work in the past, it was likely because of permissions problems.
Pgadmin probably helpfully set the permissions properly for you when it
created the file.
