How to setup a Network Plugin across the network with only my settings?

For the activation of your plugin you have to write few lines of code in the plugin.

The WordPress installation runs from wp-admin/install.php. What we are looking for is for certain actions to be triggered once the install is successful, so a good place to insert our code is right above this:

<h1><?php _e( 'Success!' ); ?></h1>

We see a code block that starts with:

if ( $error === false ) {
$wpdb->show_errors();
$result = wp_install($weblog_title, $user_name, $admin_email, $public, '', $admin_password);
extract( $result, EXTR_SKIP );

I chose to insert our actions after the last extract statement. To activate the plugins, I added:

require_once( dirname( dirname( __FILE__ ) ) . '/wp-admin/includes/plugin.php' );
activate_plugin( dirname( dirname( __FILE__ ) ) . '/wp-content/plugins/plugin-dir-name/pluginfile.php' );

And for the hiding the plugin from the list of plugin:

/**
 * Filter the list of plugins according to user_login
 *
 * Usage: configure the variable $plugin_credentials, which holds a list of users and their plugins.
 * To give full access, put a simple string "ALL"
 * To grant only for some plugins, create an array with the Plugin Slug, 
 *    which is the file name without extension (akismet.php, hello.php)
 *
 * @return array List of plugins
 */
function wdm_plugin_permissions( $plugins )
{
    // Config
    $plugin_credentials = array(
        'admin' => "ALL",
        'other-admin' => array(
            'akismet',
        ),
        'another-admin' => array(
            'akismet',
            'hello',
        ),
    );

    // Current user
    global $current_user;
    $username = $current_user->user_login;

    // Super admin, return everything
    if ( "ALL" == $plugin_credentials[ $username ] )
        return $plugins;

    // Filter the plugins of the user
    foreach ( $plugins as $key => $value ) 
    { 
        // Get the file name minus extension
        $plugin_slug = basename( $key, '.php' );

        // If not in the list of allowed plugins, remove from array
        if( !in_array( $plugin_slug, $plugin_credentials[ $username ] ) )
            unset( $plugins[ $key ] );
    }

    return $plugins;
}
add_filter( 'all_plugins', 'wdm_plugin_permissions' );

You need to modify the code as per your users roles.
