やってること

cakephp3のAuth Componentを用いてログイン認証機能を実装しています。
#困ってること
https://www.ritolab.com/entry/77
上記のサイト通りにログイン機能を実装してみたのですが、ログインができない状態になっています。

よくあるのが「パスワードがハッシュ化されていない」や「DBのpasswordの文字数が少ないからハッシュ化されても途切れてしまっている」などの問題がありますが、それらの問題はおきていません。
passwordもvarchar(255)で設定していますし、DBをみてもpasswordはしっかりとハッシュ化されています。

下記コードにログインに関連数部分を載せますので、回答いただけたら幸いです。
