Specifying username in UPN syntax?

[mrichman]

Is it possible to get an overload to pass a username in UPN syntax (i.e. username@domain.local) instead of the SAM name (i.e. DOMAIN\username)?

using (Impersonation.LogonUser(upn, password, LogonType.Interactive))
{ ... }

I'm starting to use Windows 2016 domain controllers and servers, and I can't guarantee there will be a SAM-compatible name forever.

I think I just answered my own question.

"If you use the user principal name (UPN) format, User@DNSDomainName, the lpszDomain parameter must be NULL"
