Zabbix 6.2 API Change

[Legends0]

Zabbix Plugin will not be compatible once 6.4 is released.

In 6.2, the use of the "user" parameter for authentication was deprecated and the addition of a "username" parameter that would be its replacement was added. As of beta 5 of 6.4, the "user" parameter no longer exists and the "username" parameter must be used instead.

In order to continue supporting Zabbix, the plugin needs to be able to use the new "username" parameter. This may require additional code for supporting multiple versions of Zabbix API such as through a try/catch, or version selection/detection.

Adding back the removed line on Zabbix end in file /usr/share/zabbix/include/classes/api/services/CUser.php seems to be a workaround:

public function login(array $user) {
                $api_input_rules = ['type' => API_OBJECT, 'fields' => [
                        'user' =>       ['type' => API_STRING_UTF8, 'flags' => API_DEPRECATED, 'replacement' => 'username', 'length' => 255],
                        'username' =>   ['type' => API_STRING_UTF8, 'flags' => API_REQUIRED, 'length' => 255],
                        'password' =>   ['type' => API_STRING_UTF8, 'flags' => API_REQUIRED, 'length' => 255],
                        'userData' =>   ['type' => API_FLAG]
                ]];
