If you can upgrade the above to the latest, that would be a good thing.  
Especially postgresql.  At the very least, upgrade postgresql to 7.2.5 or 
whatever the last version of 7.2 was.

How are logins handled, via apache authentication, or custom PHP code?

do you mean apache / web site authentication, or pgsql authentication is 
failing?

You might want to try setting it to just trust on local and host 
127.0.0.1/255.0.0.0 for testing to see if that lets you in.

If you make a simple page that has this in it:

<?php
phpinfo();
?>

what do you get (look in the apache httpd.conf file for the extensions 
php is setup to handle.  you may need to edit this and restart apache.

If auth.php is not finding the db, what kind of error is it giving.  
More details make it easier to troubleshoot your problem.

Not a problem.  While the function name is deprecate, it is still 
supported, at least through php 4.3.4, which I'm running on my 
workstation:

$ php -v
PHP 4.3.4 (cli) (built: Dec  4 2003 11:34:30)
Copyright (c) 1997-2003 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2003 Zend Technologies
$ php -q
<?php
pg_exec();
?>
PHP Warning:  Wrong parameter count for pg_exec() in - on line 2

Warning: Wrong parameter count for pg_exec() in - on line 2

So it sees it as a valid command.
