我正在经历使用LDAP授权设置RabbitMQ的过程，但运气不太好...有没有知情的人帮我看看，告诉我哪里做错了？我可以使用以下代码查询LDAP以获取用户对象：

var entry = new DirectoryEntry("LDAP://ourldapbox.ourcompany.co.uk:636/CN=Mark Twain,OU=Development,OU=OurCompany Employees,DC=OurCompany,DC=co,DC=uk");

连接编码

我尝试了几种方法连接（都失败了）：

var connectionFactory = new ConnectionFactory
{
    HostName = "localhost",
    UserName = "twainm",
    Password = "fred123",
};

using (connectionFactory.CreateConnection())
{
    // fails with:
    // None of the specified endpoints were reachable
    // ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.
}

内部数据库回退配置正在工作，因此guest能够顺利连接。

我有一个很好的谷歌“LDAP绑定错误”，“handshake_error，starting，0”和“access_rejected”，但找不到任何可以指向我正确的方向。
如果你能帮忙的话，我将不胜感激。
