Ios 重复令牌更新设备请求

我注意到，在安装配置文件后的MDM注册期间，设备会发送重复的令牌更新请求

首先，验证什么是可以的：

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">  
<plist version="1.0">  
<dict>  
    <key>MessageType</key>  
    <string>Authenticate</string>  
    <key>Topic</key>  
    <string>com.apple.mgmt.External.c708ft49-9595-4bd0-a6e2-9d9f234c5458</string>  
    <key>UDID</key>  
    <string>e446679f06cb220e056bf57gf4518735beb2a775</string>  
</dict>  
</plist>

下面是令牌更新：

从服务器返回200后，我再次收到具有相同值的令牌更新：

有人有过同样的问题吗？为什么要复制呢。我在IOS 6、7和8上观察到了这种行为。那么这是苹果的bug还是我做错了什么？

第二个有效负载中的另一个解锁令牌是不同的，但是我仍然不明白为什么它会被发送两次……你在使用哪个MDM？我正在创建自己的MDM服务器。所有这些都符合iOS文档3个阶段的要求。这一切都很好，但我不明白为什么签入令牌更新是2次。有什么想法吗？
