LDAP - 上下文源的 AD 用户名密码配置

Question

我正在使用 Spring 安全性来使用 LDAP 协议对 Active Directory 进行身份验证。以下代码也适用于身份验证和设置 LDAP 模板 (springSecurity.xml) :

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/security"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
            xmlns:context="http://www.springframework.org/schema/context"
            xmlns:beans="http://www.springframework.org/schema/beans" 
            xmlns:ldap="http://www.springframework.org/schema/ldap"
            xsi:schemaLocation="
            http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.1.xsd
            http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
            http://www.springframework.org/schema/context 
            http://www.springframework.org/schema/context/spring-context.xsd 
            http://www.springframework.org/schema/ldap 
            http://www.springframework.org/schema/ldap/spring-ldap.xsd">

    <http use-expressions="true">

        <intercept-url pattern="/login" access="permitAll" />
        <intercept-url pattern="/authenticated" access="isAuthenticated()" />

        <form-login login-page="/login" default-target-url="/authenticated"
            authentication-failure-url="/login?error=true" />
        <logout />


    </http>

    <beans:bean
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <beans:property name="location">
            <beans:value>classpath:/ldap.properties</beans:value>
        </beans:property>
        <beans:property name="SystemPropertiesMode">
            <beans:value>2</beans:value> <!-- OVERRIDE is 2 -->
        </beans:property>
    </beans:bean>

    <beans:bean id="adAuthenticationProvider"
        class="org.springframework.security.ldap.authentication.ad.ActiveDirectoryLdapAuthenticationProvider">
        <beans:constructor-arg value="${sample.ldap.domain}" />
        <beans:constructor-arg value="${sample.ldap.url}" />
        <beans:property name="useAuthenticationRequestCredentials"
            value="true" />
        <beans:property name="convertSubErrorCodesToExceptions"
            value="true" />
    </beans:bean>


    <authentication-manager>
        <authentication-provider ref="adAuthenticationProvider" />
    </authentication-manager>

<!--  Ldap after authentication -->

    <context:property-placeholder location="classpath:/ldap.properties"
        system-properties-mode="OVERRIDE" />
    <context:annotation-config />

    <ldap:context-source id="contextSource" 
                        password="${sample.ldap.password}"
                        url="${sample.ldap.url}" 
                        username="${sample.ldap.userDn}" 
                        base="${sample.ldap.base}"
                        referral="follow" />

    <ldap:ldap-template id="ldapTemplate"
        context-source-ref="contextSource" />

    <ldap:repositories base-package="com.domain" />

    <beans:bean class="com.service.UserService">
        <beans:property name="directoryType" value="${sample.ldap.directory.type}" />
    </beans:bean>

    <!-- Required to make sure BaseLdapName is populated in UserService -->
    <beans:bean
        class="org.springframework.ldap.core.support.BaseLdapPathBeanPostProcessor" />

</beans:beans>

从 login.jsp 获取 j_username 和 j_password 时身份验证工作正常。要设置 ldap 模板，我使用属性文件中定义的用户名和密码属性，但我希望使用来自 spring 安全性的相同用户名和密码。请指导我如何将 ldap:context-source id="contextSource" 中的用户名和密码属性属性绑定到 spring 安全凭证。

代码有点乱，欢迎大家改进。

如参考文档的 Configuration chapter 中所述，您可以通过在配置中指定自定义 authentication-source-ref 来为 ContextSource 使用 Spring 安全身份验证上下文源的元素。在您的情况下，您将使用 SpringSecurityAuthenticationSource，附带 Spring 安全性。

<ldap:context-source id="contextSource" 
                    url="${sample.ldap.url}" 
                    base="${sample.ldap.base}"
                    referral="follow" 
                    authentication-source-ref="authenticationSource"/>

<bean id="authenticationSource"
     class="org.springframework.security.ldap.authentication.SpringSecurityAuthenticationSource" />
