我擁有了你做同樣的敲打，我的頭抵牆式體驗，並最終寫入，做一個LDAP自定義身份驗證提供者針對Active Directory服務器進行查詢。
所以我的安全相關的豆類：
<beans:bean id="contextSource"
class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
<beans:constructor-arg value="ldap://hostname.queso.com:389/" />
</beans:bean>
<beans:bean id="ldapAuthenticationProvider"
class="org.queso.ad.service.authentication.LdapAuthenticationProvider">
<beans:property name="authenticator" ref="ldapAuthenticator" />
<custom-authentication-provider />
</beans:bean>
<beans:bean id="ldapAuthenticator"
class="org.queso.ad.service.authentication.LdapAuthenticatorImpl">
<beans:property name="contextFactory" ref="contextSource" />
<beans:property name="principalPrefix" value="QUESO\" />
</beans:bean>
然後LdapAuthenticationProvider可疑類：
/**

* the passed-in credentials; of note, when used with the custom {@link LdapAuthenticatorImpl},
* does <strong>not</strong> require an LDAP username and password for initial binding.

*/
public class LdapAuthenticationProvider implements AuthenticationProvider {
private LdapAuthenticator authenticator;
public Authentication authenticate(Authentication auth) throws AuthenticationException {
// Authenticate, using the passed-in credentials.
DirContextOperations authAdapter = authenticator.authenticate(auth);
// Creating an LdapAuthenticationToken (rather than using the existing Authentication
// object) allows us to add the already-created LDAP context for our app to use later.
LdapAuthenticationToken ldapAuth = new LdapAuthenticationToken(auth, "ROLE_USER");
InitialLdapContext ldapContext = (InitialLdapContext) authAdapter

}
public LdapAuthenticator getAuthenticator() {

}
public void setAuthenticator(LdapAuthenticator authenticator) {
this.authenticator = authenticator;
}
}
然後LdapAuthenticatorImpl類：

}
}
/**

最後，LdapAuthenticationToken類：

* authenticate the user.
* </p>
*
* <p>
* When this is the Authentication object stored in the Spring Security context, an application

你會注意到，有一些你可能不需要的位。
例如，我的應用程序需要保留成功登錄的LDAP上下文以供用戶在登錄後進一步使用 - 該應用程序的目的是讓用戶通過其AD憑據登錄，然後再執行AD-相關功能。因此，我有一個自定義身份驗證令牌LdapAuthenticationToken，它傳遞給我（附加LDAP上下文，而不是Spring的默認身份驗證令牌）。在LdapAuthenticationProvider.authenticate（）中，我創建了該令牌並將其傳回;在LdapAuthenticatorImpl.authenticate（）中，我將登錄的上下文附加到返回對象，以便它可以添加到用戶的Spring認證對象中。
此外，在LdapAuthenticationProvider.authenticate（）中，我爲所有登錄用戶分配了ROLE_USER角色 - 這就是讓我在我的攔截url元素中測試該角色的原因。無論您想要測試哪種角色，您都希望進行匹配，甚至可以根據Active Directory組或其他角色分配角色。
最後，由此推論，我實現LdapAuthenticationProvider.authenticate（）的方式爲所有用戶提供了有效的AD帳戶，它們具有相同的ROLE_USER角色。顯然，在該方法中，您可以對用戶（即特定AD組中的用戶？）執行進一步測試，並且甚至在准許用戶訪問全部之前分配角色，甚至測試某些條件。
這不是一個真正的答案，而是一個澄清的問題 - 您是否已經將日誌記錄轉換爲Spring安全包的所有內容？ – 2008-09-17 17:52:40
我有日誌記錄開啓了一切。沒有看到任何正在記錄的消息......我用我的Log4J配置更新了我的問題。 – Michael 2008-09-17 18:35:26
