When trying to execute a command over SSH I get:
SSH: EXEC: STDOUT/STDERR from command [.../some.exe
] ...
AllowDesktopAccess failed.
Unable to execute command or shell on remote system: Failed to Execute process.

This seems like a bug because SSH seem to work otherwise:
1. Transferring files with Jenkins over SSH works fine.
2. Executing commands from PuTTy, from my other Windows machine works (it is a bit slow, but works).
3. Executing commands from the computer Jenkins is on (over command line ssh client) also works.

Currently FreeSSHd is running as a service and I've set up logging in with Windows auth, but auth itself seem to be working fine even with Jenkins (test of setup passed, transferring files works fine).
