Я хотел бы выполнить аутентификацию со SPNEGO. Я использую:

spring-core-3.1.0.RELEASE.jar spring-security-core-3.1.0.RELEASE.jar spring-security-kerberos-core-1.0.0.M2.jar package codec from spring core security 3.0.7 (https://jira.springsource.org/browse/SES-98) tomcat

Мой файл конфигурации выглядит следующим образом. Когда я пытаюсь выполнить аутентификацию с помощью вышеуказанных библиотек, я получаю следующее исключение.

Была ли у кого-то такая же проблема и справилась?

Файл конфигурации (взят из примера Spring Security Kerberos):
