I am running Cygwin (i686 / 32-bit) on Windows 2012 R2 in an Active
Directory environment; the version in use is
> $ uname -a
> CYGWIN_NT-6.3-WOW (redacted) 2.0.2(0.287/5/3) 2015-05-08 17:03 i686
> Cygwin
OpenSSH version is
> $ ssh -V
> OpenSSH_6.8p1, OpenSSL 1.0.2a 19 Mar 2015
For internal reasons in my organization, I cannot upgrade to the current
version of Cygwin at present.
Following the installation instructions for sshd as a service (i.e., run
ssh-host-config and follow the prompts), I end up with a system running
sshd, that closes connections immediately after authentication. DEBUG3
output from ssh client and server follows:
> $ ssh -vvv localhost

I have verified the service user running SSHD has the permissions
required (to my knowledge, "Create Token" and "Login as Operating
System" as well as membership of the local computer's Administrators
group). I have verified /var/empty has appropriate ownership and
permissions. I have checked the shell's configuration files; running a
local shell on the system through the cygwin terminal works fine. I have
no idea what else to look at, and would appreciate any help at this point.
