Windows whoami returns hostname\sshd_server after ssh auth key login

I installed the snapshot with Corinna's fix and now I get an entirely
different user (system):

Administrator@am-inst-das-win ~
$ ssh Administrator@am-inst-das-win "C:/Windows/system32/whoami"
nt authority\system

Adding Administrator to the Administrators group in /etc/group does not
change any behavior either.  My /etc/group file:

Administrator@am-inst-das-win ~
$ cat /etc/group
