Re: [ADMIN] phpPgAdmin + PostgreSQL + authentication

--howdy:

--i'm doing a few tests on it, and one of the drawbacks

--sql on it (the joins between multiple table, heavy
--calculations, etc).

--i tried to do something like that in a report (didn't see
--how else i could do it) and my browser timed out
--the query kept running!

--i really would like to find a nice alternative (like pgAdmin II ).
--i've tested a few, but most of them don't handle md5
--encryption and the others want python installed
--(and at compile time when building postgreSQL ... i just
--can't do that right now ... ).

--if anyone can suggest some product that can do

--a windows environment, i'd be grateful for the information.

We are. I love it.

I specifically disallow local, because we're about to switch to kerberos
as our auth mechanism.

In your case, I think you want md5 here as well.

I believe it does.

Advance auth requires you to have these two entries:
$cfgServers[1]['stduser'] = 'auth';
$cfgServers[1]['stdpass'] = 'adv_auth';

Obviously, where stduser and stdpass are specific to your site.

What happens is pgadmin needs someway to confirm or deny that a given
user can login to the database, and so has to use this "other"
user/password to connect.

I think thats whats happening, anyway.
