Christopher,

Your theory is apparently correct.

One workaround you might try is allowing the sshd service to interact with
the desktop (by checking the appropriate box) and mounting the share as
the logged-on user.  What others reported as a "security problem" (that a
user can access other users' shares through Cygwin) could be a solution
for you.
