問題

  • LiferayをLiferay DXP 7.0からLiferay DXP 7.2にアップグレードした後、SAMLが機能しなくなり、ユーザーがSAMLを使って認証できなくなりました。 Identity Providerだけでなく、Service Providerのログにも、それぞれ以下のエラーが表示される可能性があります。

環境

  • Liferay DXP 7.0+

解決

  • Liferayをあるバージョンから別のバージョンにアップグレードする場合、ユーザーは古いバージョンで生成されたSAML証明書を新しいバージョンに移行するか、新しいバージョンでSAML証明書を更新する必要があります。そうしないと、アップグレードプロセス後にSAMLが機能しなくなります。これは、Liferayがこれらのファイルを参照する際に、Liferayインストールを基準とした相対パスを使用するため、古いバンドルではなく新しいバンドル内のファイルを検索するためです。
  • 古いバージョンのLiferayから新しいバージョンのSAML証明書を移動するか、新しいバージョンのSAML証明書をリフレッシュすると、SAMLが再び動作し始め、ユーザーが認証できるようになるはずです。
