1) Required - The LoginModule is required to succeed.
If it succeeds or fails, authentication still continues
to proceed down the LoginModule list.

The overall authentication succeeds only if all Required and Requisite LoginModules succeed.
If a Sufficient LoginModule is configured and succeeds, then only the Required and
Requisite LoginModules prior to that Sufficient LoginModule need to have succeeded
for the overall authentication to succeed.
必須の loginModule が失敗した場合、結果は失敗になるようです。私の質問は、Required loginModule が失敗した場合でも、認証が引き続きLoginModule リストを下に進むのはなぜですか?
