OLE "DB login failed" for SSIS job through SSH

I have an SSIS job that I need to activate via ssh. SSH service is BitVise. I am able to connect using keys generated on my unix host.

I run the following script on my unix host:

#!/usr/bin/env bash

# expects host configuration in ~/.ssh/config
# Host ssis-test
#     HostName SSISTEST
#     User WINDOWSUSER
#     Port 22
#     IdentityFile /home/foo/.ssh/ssis_dsa
#     PasswordAuthentication no
#
ssh ssis-test "D:\\Airflow\\run-ssis.bat"

. . . which simply calls a script on the windows host.

I then see the following error:

The script works fine when I call it from a command prompt when logged into my windows host via winrm.

It appears that when I log in via ssh, whatever mechanism OLE uses to get my domain\username is not being properly tickled. How do I let OLE know who I am before running my SSIS batch?
