No. The solution is in fact, don't use rshd but sshd. rshd is for reasons often mentioned in this mailing list not able to change the user context. That's a problem! Using ssh and sshd with RSA key _is_ definitely the better way - not only for security reasons (/usr/doc/Cygwin/openssh-2.3.0p1.README). There is another way, though. Start inetd from the user account which shall run rshd and the subshell. And don't forget to set the user permissions then (/usr/doc/Cygwin/inetutils-1.3.2.README).
