Does "getent passwd" display any active domain+accounts on your system?
If someone is logged on to that system from a domain+account?
Check your domain membership:
$ echo $USERDOMAIN $USERDOMAIN_ROAMINGPROFILE
and any other DOMAIN environment variables you have, and explicitly specify a
known account in that domain before the userid using a plus sign "+" separator:
$ getent passwd domain+account
similar to Trusted Installer:
$ getent passwd nt\ service+trustedinstaller
NT SERVICE+TrustedInstaller:*:328384:328384:U-NT
SERVICE\TrustedInstaller,S-1-5-80-...:/:/sbin/nologin
If the account doesn't display, check you are using the correct domain
membership using AD DS tools or e.g a PowerShell script.
