i did some investigation in the code, especially
at first i tried to alter example.php according to my needs (user, pwd, server-uri), but it didnt work. i got: "SOAP Error: The login failed. Username or password wrong."
so i took a look into remoting.inc.php and found something i dont understand. the script tries to find the user/pwd in the database-table "remote_user" - which is empty on my setup. after adding a dummy-user with md5(pwd) the example.php-script told me that logging in and logging out was successfully. so i consider the "soap-part" is working properly.
the next step ill do is, to make remoting.inc.php look for the user/pwd in the database-table "sys_user". when a user/pwd is found ill create a session just like its done in /web/login/index.php.
maybe im on the very wrong way, but I really dont have any clue whats that "remote_user"-table about - so any hint or some suggestions from the devs would be very nice
