Thank you for these examples.
I created the file /var/www/fog/lib/hooks/mobileusernologin.hook.php and pasted your first code, then changed the userLogginIn function with your 2 other codes (and replacing “username1” by “fog”), but I didn’t see any difference in each case: when logging to http://…/fog/management/index.php whith either “fog” account or a “test” account, I still see all the menus.
What am I doing wrong ?

I understood that hooks are like plugins which can be added and activated with “public $active = true;” inside the php file.
I search for USER_TYPE in the sources files and only find them in these files :
/lib/plugins/ldap/hooks/ldappluginhook.hook.php

        self::$HookManager
            ->register(
                'USER_LOGGING_IN',
                array(
                    $this,
                    'checkAddUser'
                )
            )
            ->register(
                'USER_TYPE_HOOK',
                array(
                    $this,
                    'setLdapType'
                )
            )
            ->register(
                'USER_TYPES_FILTER',
                array(
                    $this,
                    'setTypeFilter'
                )
            )
            ->register(
                'USER_TYPE_VALID',
                array(
                    $this,
                    'isLdapType'
                )
            );

/lib/fog/user.class.php

        $type = $tmpUser->get('type');
        self::$HookManager
            ->processEvent(
                'USER_TYPE_HOOK',
                array(
                    'type' => &$type
                )
            );
        self::$HookManager
            ->processEvent(
                'USER_TYPE_VALID',
                array(
                    'type' => &$type,
                    'typeIsValid' => &$typeIsValid
                )
            );
        if ($typeIsValid && !in_array($type, array(0, 1))) {
            $typeIsValid = false;
        }

            if (self::$FOGUser->isValid()) {
                $type = self::$FOGUser->get('type');
                self::$HookManager
                    ->processEvent(
                        'USER_TYPE_HOOK',
                        array('type' => &$type)
                    );
                $this
                    ->set('id', self::$FOGUser->get('id'))
                    ->set('name', self::$FOGUser->get('name'))
                    ->set('password', '', true)
                    ->set('type', $type);
                if (!$this->_sessionID) {
                    $this->_sessionID = session_id();
                }

/lib/pages/processlogin.class.php

        $type = self::$FOGUser->get('type');
        self::$HookManager
            ->processEvent(
                'USER_TYPE_HOOK',
                array('type' => &$type)
            );

But I don’t really understand what this code do and what is the link with my aim (having a restricted web interface for a specific user).

The only lead I see is in the first file which talks about an unprivileged user account (with type=“991”)

            $access = $ldap->authLDAP($user, $pass);
            unset($ldap);
            switch ($access) {
            case 2:
                // This is an admin account, break the loop
                $tmpUser
                    ->set('name', $user)
                    ->set('password', $pass)
                    ->set('type', 990)
                    ->save();
                break 2;
            case 1:
                // This is an unprivileged user account.
                $tmpUser
                    ->set('name', $user)
                    ->set('password', $pass)
                    ->set('type', 991)
                    ->save();
                break;
            default:

Is type “991” the key ? or does it only concern ldap ?

I don’t know what hooks are and where I can find USER_TYPE_HOOK and USER_TYPE_VALID.
Is it in the database ? (I only found a field named Type in the Users table which is equal to 0).

Is it this one ?

Ok, so I can’t let teachers restore an image without giving them all access to the web interface. It’s a shame.

Hello,
I just installed the latest version of Fog and I can’t access to …/fog/mobile.
Does the Mobile Interface still exist ?

@george1421 I’m using dnsmasq 2.76.
I just tried your ltsp.conf file and it works.
Thank you very much.

Hello,

I did a fresh install of Debian 9 following this page : https://wiki.fogproject.org/wiki/index.php?title=Debian_8
Then I followed Install dnsmasq on CentOS 7 (https://wiki.fogproject.org/wiki/index.php?title=ProxyDHCP_with_dnsmasq) as my DHCP server is a home internet box.

During FOG setup, I didn’t choose any DHCP/DNS option (seen here : https://wiki.fogproject.org/wiki/index.php?title=Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server).

Now when I boot a PC client, DHCP works (IP found) but it doesn’t boot (PXE-T01: File not found, PXE-E3B : TFTP Error - File Not found)

/etc/dnsmasq.d/ltsp.conf contains this : https://framabin.org/?98496140ffa228a1#FNmhScXt0cwbQm8ya2SY2AYRhjcRdlTRX4zksG3drwI=
/tftpboot contains this : https://framabin.org/?cf5d1f8abaff3b10#dUhgKqKg8r/Opl32tHKEgTyev40sIdhUlWTgoHC0qGs=
PC and FOG server are Lenovo ThinkCentre M79

Have you got an idea of what is wrong ?
