also its realy easy to make common logins from other applications with vbulletin ( and this addon )

look at the examples in the package

in the login.php you can find code to "login" on vbulletin

as result you will get all needed cookies ($connection->_cookies)

you must just walt this array and set cookies

PHP Code:

                            foreach( $connection->_cookies AS $name => $value)
                            {
                                              setcookie($name, $value[0], $lifetime, $value[1], $value[2]);
                            } 


if you have set all this cookies, the user will be logged in vbulletin
