Cygwin+OpenSSH on XP: Scheduled SFTP job fails - but manual runs fine

[Eugene F.]

I have Cygwin+OpenSSH installed on Windows XP workstation.

Simple SFTP process (batch file) runs fine when launched from the
Command Prompt and fails when launched by a Scheduler from Novell
Desktop Management. Scheduled job uses _exactly the same_ batch file
and runs as Interactive User impersonation.

WhoAmI embedded in the batch file returns the same user string. Cygwin
itself called from a scheduled job shows the same user id in the
prompt as when launched directly from the desktop icon.

I get the following error from a scheduled sftp job:

"Permission denied (publickey,keyboard-interactive).
Connection closed"

Any suggestions for further troubleshooting?

TIA, Eugene
