1. 使用几个废弃的遥控器（遥控器得是好的
2. 墙壁开关按到关灯10秒后开灯，开灯3秒内对着灯按遥控器上的任意键，灯自动闪三次后设置成功(有可能没反应, 不过没关系)
3. 再次继续关灯10秒后开灯，开灯3秒内按遥控器上的其他按键
4. 设置4次之后按电视遥控器检测是否有影响
5. 这样设置过后, 之前电视遥控器应该就不能在遥控灯了

How to configure supported browsers for Kerberos and NTLM
Published: 01/25/2018

The PingFederate Integrated Windows Authentication (IWA) Adapter supports the Kerberos and NTLM authentication protocols, but some browsers need to be configured to utilize them.  The following guide will define which settings are necessary in each browser.

For Kerberos and NTLM authentication, the PingFederate IWA Adapter utilizes the SPNEGO (Simple and Protected GSS-API Negotiation) mechanism to negotiate either Kerberos or NTLM as the underlying authentication protocol.  Each browser below supports SPNEGO, but differences exist that may affect which protocol is negotiated in each instance, due to the combination of browser and OS.

The PingFederate IWA Adapter supports the following browsers:
