MacOS版Office 365（16.84）WebDAV认证异常及支持类型咨询

我在PHP应用中开发了WebDAV功能，采用Basic认证进行用户身份识别，对未认证请求返回响应头：
WWW-Authenticate: Basic realm=example, charset="UTF-8"

近期发现WebDAV编辑功能失效，排查后确认仅在MacOS版Office最新版本（从16.81升级至16.84）中出现问题：MS Word不再发送Authorization: Basic XXX，而是发送Authorization: Bearer (空值)。登录请求弹窗仍会弹出，但凭证并未被发送。

有几个问题想请教：

• 微软是否已禁用Basic认证支持？
• 除了实现其他认证方案外，是否有其他解决办法？
• 当前版本支持哪些认证方案？

MS Word发送至服务器的可用认证类型如下：

"accept-auth": [ "badger,Wlid1.1,Bearer,Basic,NTLM,Digest,Kerberos,Negotiate,Nego2" ]

完整客户端请求头：

{ 
  "host": [ "default.stage-wiki.vpool.qsoft.ru" ], 
  "x-real-ip": [ "10.42.0.183" ], 
  "x-forwarded-for": [ "10.42.0.183, 10.42.0.183" ], 
  "connection": [ "close" ],
