春季安全性LDAP-。认证失败

Question

我在auth上使用Spring Security 4。

这是我的配置

<?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:beans="http://www.springframework.org/schema/beans"
             xsi:schemaLocation="

    <http auto-config="true" use-expressions="true">
        <intercept-url pattern="/" access="permitAll"/>
        <intercept-url pattern="/home" access="permitAll"/>
        <intercept-url pattern="/login" access="permitAll"/>
        <intercept-url pattern="/secure" access="isAuthenticated()"/>

        <form-login login-page='/login' default-target-url="/" authentication-success-forward-url="/secure" authentication-failure-url="/login?error" />
        <logout logout-success-url="/" />
    </http>

    <authentication-manager>
        <ldap-authentication-provider
                user-search-base="ou=Users"
                user-search-filter="(uid={0})"
                group-search-base="ou=groups"
                group-search-filter="(member={0})"
        >
        </ldap-authentication-provider>
    </authentication-manager>

    <ldap-server id="contextSource"
                 url="ldap://myip:389/"
                 root="OU=Users,DC=mydomain,DC=local" />
</beans:beans>

由以下原因引起：javax.naming.NamingException：[LDAP：错误代码1-000004DC：LdapErr：DSID-0C09075A，注释：为了执行此操作，必须在连接上完成成功的绑定。数据0，v1db1 ];剩余名称'ou = Users'

我怎么了？
