我正在经历使用 LDAP 授权设置 RabbitMQ 的过程，但运气不佳......知道的人可以看看并告诉我我做错了什么吗？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");

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

我正在尝试以多种方式进行连接（均失败）：

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能够毫无问题地连接。

对于“LDAP 绑定错误”、“handshake_error,starting,0”和“access_refused”，我有一个很好的 Google，但找不到任何可以为我指明正确方向的东西。

任何帮助，将不胜感激。

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

这是我的 LDAP 配置（现在可以使用）。我希望这可以为一些人节省几个小时：

[
  {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}
   ]
  }
].

我有一个类似的问题，除了我使用的是 rabbitmq.conf 而不是 advanced.config 格式。如果有人遇到此问题并使用其他配置格式，这是一个替代解决方案：

auth_backends.1 = ldap    
auth_ldap.servers.1  = ourldapbox.ourcompany.co.uk
auth_ldap.dn_lookup_attribute = sAMAccountName
auth_ldap.dn_lookup_base = DC=ourcompany,DC=co,DC=uk
auth_ldap.user_dn_pattern = ${username}@ourcompany.co.uk
auth_ldap.use_ssl    = true
auth_ldap.port       = 636
auth_ldap.log        = true
auth_backends.2   = rabbit_auth_backend_internal
