cyrus how-to

Hi pecl-list, I've just installed the cyrus extension by the pear installer on a Debian Woody Linux. After installing some dev-packages I got it successfully ;-) Looking at the php manual I only got a "This function is currently not documented; only the argument list is available." :-( I know how to work with cyrus using the "cyradm shell", so I don't need a cyrus tutorial. I just would like to know how to authenticate to cyrus and then how to send a query. Is there a way to get the query result from cyrus, eg to get info about quota? I tried this with the CLI, but it didn't work, the mailbox 'phptest' wasn't created by cyrus: <?php $c = cyrus_connect("localhost"); if ($c === false) { die("Error: couldn't connect to cyrus.\n"); } echo "connected to cyrus\n"; $a = cyrus_authenticate($c, "", "", "cyrus"); // $a = NULL here $success = cyrus_query($c, "cm user.phptest"); // $success = true cyrus_close($c); echo "finished.\n"; ?> I guess my authentication is wrong, but I don't know what the parameters stands for at all... Any help would be very appreciated. Regards, Matthias
