LDAP의 봄 보안 문제 | 오류 코드 32-해당 개체 없음

내 응용 프로그램에서 봄 보안을 설정하려고합니다. 스프링 보안 XML을 구성했습니다. 로그인을 시도 할 때 아래 오류가 발생합니다.

스프링 보안에 대한 내 XML 구성은 다음과 같습니다.

<security:authentication-manager>
            <security:ldap-authentication-provider  
                    user-search-filter="(uid={0})" 
                    user-search-base="ou=Users,dc=maxcrc,dc=com"
                    group-search-filter="(roleOccupant={0})"
                    group-search-base="ou=Groups,dc=maxcrc,dc=com"
                    group-role-attribute="cn"
                    role-prefix="ROLE_">
            </security:ldap-authentication-provider>
    </security:authentication-manager>

    <security:ldap-server url="ldap://localhost:389/o=blah" manager-dn="cn=Manager,dc=maxcrc,dc=com" manager-password="secret" />

내 LDAP 구조는 다음과 같습니다.

문제를 이해할 수 없습니다. 어떤 도움을 주시면 감사하겠습니다.
