Community Auth - a database error when logging in

#1
Hi,

I have installed Community Auth (current master) with CodeIgniter 3.1.4.

The configurations are:



Code:
$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = sys_get_temp_dir();
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;

Added an encryption key using Key_creator.php

Edited Examples.php


Code:
public function create_user()
{
// Customize this array for your user
$user_data = [
'username'   => 'skunkbot',
'passwd'     => 'PepeLePew7',
'email'      => '[email protected]',
'auth_level' => '9', // 9 if you want to login @ examples/index.
];



An account is created using /examples/create_user

Checked the DB user table and the user exists





However when I try to login, I get a database error:

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, '309003055', '2017-04-10 14:11:54', '84.92.55.111', 'Chrome 57.0.2987.133 on Mac OS X')
Filename: third_party/community_auth/models/Auth_model.php
Line Number: 90



$session_id seems to be NULL..

Do you have any idea why it keeps getting this error?

Thanks.

Can you verify that the session actually exists in the location you are attempting to store it?

sys_get_temp_dir() is your location. The id of auth_sessions is the CI session ID, and it's only NULL because that's what's being passed to it from the CI session library.

My advice is to make sure plain CI sessions are working with your application, and you'll probably see that Community Auth starts working.

Thanks for your reply.

I have tested with the following:

Code:
public function test()
{
  $this->load->library('session');
  $this->session->set_userdata(array( 'username' => 'testuser', 'logged' => TRUE));
  var_dump($_SESSION);
}

and I got the result:

in the browser http://mydomain.com/welcome/test

array(4) { ["__ci_last_regenerate"]=> int(1491940229) ["auth_identifiers"]=> string(81) "a:2:{s:7:"user_id";s:9:"309003055";s:10:"login_time";s:19:"2017-04-11 19:55:38";}" ["username"]=> string(8) "testuser" ["logged"]=> bool(true) }

on the server

Code:
/tmp $ sudo cat ci_sessionvg3kcrpgn7i2h0jggdbvm1j4ed64u7li
__ci_last_regenerate|i:1491940229;auth_identifiers|s:81:"a:2:{s:7:"user_id";s:9:"309003055";s:10:"login_time";s:19:"2017-04-11 19:55:38";}";username|s:8:"testuser";logged|b:1;
/tmp $

I think CI session is working fine...

The server is running Debian wheezy, nginx-1.2.1-2.2+wheezy4, php5-fpm-5.4.45-0+deb7u6, mysql-server-5.5.54-0+deb7u1
Is there anything to do with nginx? like rewrite configuration?

Thanks.

When I use your session config, all is working fine. This is on Ubuntu 16.04 with PHP7.

What is the value of your encryption key? Mine in example is like this:


PHP Code:
$config['encryption_key'] = hex2bin('5d3a06b1a1efeb861ad761fb8839794f'); 
I don't know that nginx would have anything to do with it, but my experience with it is limited. It's interesting that your session ID is returning NULL.  I suppose you'd have to debug that and see what/why/where.

If you can zip up your site, and include a current dump of your database, and make it accessible for me to download, I'd like to figure out what's going on. I'd be glad to do it.

This is what I had to do with your files to get things working:

1) Set the value of base_url in config/config to an actual domain.

2) Changed "admin" on line 41 of controllers/Examples.php to "superuser". You changed the names of the roles in config/authentication, but they are not appropriate for the examples. If you want to use the examples without altering them, then you need to change your roles back to the way they come from the Community Auth repo.

That's all it took for me to get it working.

Also, if you want to confirm things are just the way they are on my system (Ubuntu 16.04), then you can use the dev installer located at /community_auth/sh/.development_install.sh. I put that in /var/www, and then run it. I have a complete working install in about 5 seconds. I am of course using virtual hosts... but its worth a try to see if it works for you.
