@Maras0830 Sorry, can you explain what exactly is the issue that you are having?

@Zizaco
in entrust.php

    /*
    |--------------------------------------------------------------------------
    | Application User Model
    |--------------------------------------------------------------------------
    |
    | This is the User model used by Entrust to create correct relations.
    | Update the User if it is in a different namespace.
    |
    */
    'user' => 'App\User',

If my project have multiple guard identities, when I want to get role - users
that will return laravel framework config auth user table .. not the packages user table ...

because in EntrustRoleTrait.php

    /**
     * Many-to-Many relations with the user model.
     *
     * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
     */
    public function users()
    {
        return $this->belongsToMany(Config::get('auth.providers.users.model'), Config::get('entrust.role_user_table'), Config::get('entrust.role_foreign_key'), Config::get('entrust.user_foreign_key'));
    }

so I push this commit 336382e.
we should be use this packages config user table, not framework default auth user table.

The relation of multiple identities is not necessarily the same as auth user.
