<?php

namespace App\Rules;

use Illuminate\Contracts\Validation\Rule;

class NotGuestLtid implements Rule
{
    /**
     * Create a new rule instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->user = \Auth::user();

The property user does not exist. Although not strictly required by PHP, it is generally a best practice to declare properties explicitly.

    }

    /**
     * Determine if the validation rule passes.
     *
     * @param  string  $attribute
     * @param  mixed  $value
     * @return bool
     */
    public function passes($attribute, $value)
    {
        return $value != $this->user->guest_ltid;

The property guest_ltid does not seem to exist on App\User. Are you sure there is no database migration missing?

    }

    /**
     * Get the validation error message.
     *
     * @return string
     */
    public function message()
    {
        return 'The validation error message.';
    }
