Community Auth Issue

Hi, jaystream ,
I too downloaded file and I try to login through ajax.
But I saw some problems when can try to login with ajax login.

A Database Error Occurred

Error Number: 1048

Column 'id' cannot be null

INSERT INTO `auth_sessions` (`id`, `user_id`, `login_time`, `ip_address`, `user_agent`) VALUES (NULL, '2664792807', '2017-08-31 11:15:44', '::1', 'Chrome 60.0.3112.113 on Windows 7')

Filename: D:/xampp/htdocs/sites/community_auth/system/database/DB_driver.php

Line Number: 691

The problem for this is coming from id cannot be null.
you can change this table:

CREATE TABLE `auth_sessions` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`user_id` int(10) unsigned NOT NULL,
`login_time` datetime DEFAULT NULL,
`modified_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
`ip_address` varchar(45) NOT NULL,
`user_agent` varchar(60) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
