Pear and Pear AUTH -

Dear Sirs, I have Apache 2.0.48 & PHP 5.0.0RC2 & MYSQL 4.0.13-nt. First, i would like to know if there´s any difference between PEAR 4X and PEAR 5x. Second, I want to reinstall PEAR in PHP5 and I kindly ask you a small 'cake recipe' to make it work and with little workarounds. And last but not the least, i copied and pasted the below code from http://pear.php.net/manual/en/package.authentication.auth.intro.php . <?php require_once ("Auth/Auth.php"); function loginFunction() { echo "Welcome to this site ..." /** * Change the HTML output so that it fits to your * application. */ echo "<b>Here you are<b></p>"; echo "<form method=\"post\" action=\"" . $_SERVER['PHP_SELF'] . "\">"; echo "<input type=\"text\" name=\"username\">"; echo "<input type=\"password\" name=\"password\">" /*change to supply database name*/ echo "<input type=\"text\" name=\"database">"; echo "<input type=\"submit\">"; echo "</form>"; } /*username=fulano password=12345 database = mysql */ $dsn = "mysql://user:password@localhost/database"; $a = new Auth("DB", $dsn, "loginFunction"); print $a; $a->start(); if ($a->checkAuth()) { echo "Login successfull!"; /** * The output of your site goes here. */ } ?> I supply my name (fulano) and password(12345) and database (mysql). The same ones I use under DOS to query Mysql succesfully. These assignments really work fine with another front-end, namely MySQL-Front .But the page always returns nothing. In this case it should display "Login Successfull" but just prompt on and on the screen again. I wonder what I fail to understand 'cause I read lists, manuals, docs but there´s something in $dsn = "mysql://user:password@localhost/database" or somwhere else I stil can see to make it work. best regards Érico
