does ntlm authentication supports upn (userprincipalname) style of username (ex: name@domain.com)to authenticate ? hi puranjay, technically, no, functionally, yes - @ least respect performing logons. because client convert username nameuserprincipal format namesamcompatible format (part of negotiate security package). focusing on "technically, no" part, if try , call ntlm-based api function with upn wouldn't work. cheers, lain Windows Server > Security
