尝试将ldap连接到spring项目 - LDAP：错误代码32 - 无此对象

Question

我试图在我的mac上使用openldap启动并运行一个spring项目。

由于默认情况下在OSX上使用openldap安装openldap，然后使用Apache Directory studio进行配置。

我的目录如下所示：

这样的事情就是这样：

当我尝试使用nilsi和正确的密码登录时，我在Eclipse中收到错误：

我与ldap的关系如下：

<security:http auto-config="true" use-expressions="true">

    <security:intercept-url pattern="/auth/login"
        access="permitAll" />

    <security:form-login login-page="/auth/login"
        authentication-failure-url="/auth/login?error=true" />

    <security:logout invalidate-session="true"
        logout-success-url="/auth/login" logout-url="/auth/logout" />

</security:http>

<security:ldap-server url="${ldap.url}"
    manager-dn="${ldap.managerdn}" manager-password="${ldap.managerpassword}" />

属性文件：

# Ldap server settings:
ldap.url=ldap://localhost:389
ldap.managerdn=ou=users,o=backlog
ldap.managerpassword=1234
ldap.user-search-filter=(uid={0})
ldap.user-search-base=ou=users,o=backlog

slapd.conf中的DBD定义：

#######################################################################
# BDB database definitions
#######################################################################

database    bdb
suffix      "o=backlog" 
rootdn      "ou=users,o=backlog"
# Cleartext passwords, especially for the rootdn, should
# be avoid.  See slappasswd(8) and slapd.conf(5) for details.
# Use of strong authentication encouraged.
rootpw      {MD5}gdyb21LQTcIANtvYMT7QVQ==
# The database directory MUST exist prior to running slapd AND 
# should only be accessible by the slapd and slap tools.
# Mode 700 recommended.
directory   /private/var/db/openldap/backlog
# Indices to maintain
index   objectClass eq

但是，当我尝试使用我的ldap目录中不存在的帐户登录时，Spring正在使用干净的日志和无效的用户名/密码响应进行响应。

此外，如果ldap返回之前未使用过该应用程序的用户，则应用程序将自动映射具有权限的用户。所以换句话说，如果ldap只返回一个id / username，那么它应该可以工作。

我刚遇到这个问题。在可能的情况下，错误与真实管理者有关。我们的配置（适用于我们）是：

<security:authentication-manager>
            <security:ldap-authentication-provider
                    user-search-filter="(uid={0})"
                    group-search-filter="(uniqueMember={0})"
                    group-role-attribute="cn"
                    role-prefix="ROLE_">
            </security:ldap-authentication-provider>
    </security:authentication-manager>

      <security:ldap-server url="ldap://172.31.7.20:389/dc=gt,dc=local"/> 

在我们的例子中，我们不需要ldap服务器的manager-dn配置，因为我们只使用了授权和授权，但是我们不修改LDAP中的条目。

我们使用OpenLDAP作为LDAP服务器，模式为rfc2307bis
