RabbitMQ LDAP身份验证失败

Question

我正在经历使用LDAP授权设置RabbitMQ的过程,但我没有太多运气......有人知道,请看看我告诉我我做错了什么？我能够使用以下代码查询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");

配置尝试1

[
  {rabbit, [{auth_backends, [rabbit_auth_backend_ldap, rabbit_auth_backend_internal]}]},
  {rabbitmq_auth_backend_ldap,
   [ {servers,               ["ourldapbox.ourcompany.co.uk"]},
     {user_dn_pattern,       "CN=${username},OU=Development,OU=OurCompany Employees,DC=OurCompany,DC=co,DC=uk"},
     {use_ssl,               false},
     {port,                  636},
     {log,                   true}
   ]
  }
].

配置尝试2

[
  {rabbit, [{auth_backends, [rabbit_auth_backend_ldap, rabbit_auth_backend_internal]}]},
  {rabbitmq_auth_backend_ldap,
   [ {servers,               ["ourldapbox.ourcompany.co.uk"]},
     {dn_lookup_attribute,   "sAMAccountName"},
     {dn_lookup_base,        "DC=ourcompany,DC=co,DC=uk"},
     {user_dn_pattern,       "${username}@ourcompany.co.uk"},
     {other_bind,            anon},
     {use_ssl,               false},
     {port,                  636},
     {log,                   true}
   ]
  }
].

配置尝试3

[
  {rabbit, [{auth_backends, [rabbit_auth_backend_ldap, rabbit_auth_backend_internal]}]},
  {rabbitmq_auth_backend_ldap,
   [ {servers,               ["ourldapbox.ourcompany.co.uk"]},
     {dn_lookup_attribute,   "userPrincipalName"},
     {dn_lookup_base,        "dc=ourcompany,dc=co,dc=uk"},
     {user_dn_pattern,       "${username}@ourcompany.co.uk"},
     {use_ssl,               false},
     {port,                  636},
     {log,                   true}
   ]
  }
].

连接代码

我试图以多种方式连接(全部失败):

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运行,因此guest可以毫无问题地进行连接.

我有一个很好的谷歌"LDAP绑定错误","handshake_error,开始,0"和"access_refused",但找不到任何可以指向正确方向的东西.

任何帮助,将不胜感激.

Answer 1

解决了!我意识到组合use_ssl=false和port=636有点愚蠢,因为636是加密(即SSL LDAP)端口.

这是我的LDAP配置(现在正在运行).我希望这可以节省一些人几个小时:

[
  {rabbit,
   [ {auth_backends, [rabbit_auth_backend_ldap, rabbit_auth_backend_internal]}]},
  {rabbitmq_auth_backend_ldap,
   [ {servers,               ["ourldapbox.ourcompany.co.uk"]},
     {dn_lookup_attribute,   "sAMAccountName"},
     {dn_lookup_base,        "DC=ourcompany,DC=co,DC=uk"},
     {user_dn_pattern,       "${username}@ourcompany.co.uk"},
     {use_ssl,               true},
     {port,                  636},
     {log,                   true}
   ]
  }
].
