This is my case: using local accounts only.

Reminder: sshd did work w/ 2.11.2 ...
(and it works now in 3.0.1 after replacing cyg_server w/ SYSTEM (*) )

Way back I started using cyg_server because "csih" forced me to create
this privileged account (W7!).

I studied "csih" (cygwin-service-installation-helper.sh) again ...

64-@@# editrights -u cyg_server -l
SeAssignPrimaryTokenPrivilege
SeCreateTokenPrivilege
SeServiceLogonRight
SeDenyInteractiveLogonRight
SeDenyRemoteInteractiveLogonRight

Compared to "csih", the SeTcbPrivilege privilege was missing. I am not
in the habit of messing with privileges ...

Consequently, like you, I am stumped too :-)

(*) after "moving" the sshd service from cyg_server to SYSTEM, I also
changed the ownership of /var/empty and /etc/ssh* (to SYSTEM) ...

Next, I disabled the cyg_server and sshd accounts. ssh still works.
