如何区分本地用户和域用户，这些用户是我的凭据提供程序的登录屏幕上缓存的磁贴

Question

I am developing a credential provider in windows and in the credential provider I am invoking another.exe and I need to pass username as argument in UPN format ie for local user: user@machineName and for domain user: user@domainName . Here the problem is for cached tiles on login screen in windows, how can I know if the cached user trying to login from my credential provider is domain user or local user?

Answer 1

I figured out that I am getting the domain name along with user name in _pszQualifiedUserName in the flat name format ie Domain\username in GetSerialization() which should help me to differentiate between domain and local user.
