[scponly] Unable to launch sftp-server from chroot: request denied

[John Barton]

All,
I am trying to get scponly version 4.1 running on Solaris 8 sparc, and I 
am having trouble that seems to be specific to sftp-server.

If I try to use WinSCP in "scp" mode, I can connect without any trouble, 
and I am properly chrooted into my home directory.

If I try to use WinSCP in "sftp" mode, it fails with the following 
error: "Connection has been unexpectedly closed. Server sent command 
exit status 1". On the server side, in the messages log, it just says 
"denied request: /opt/xxx/bin/sftp-server (resolved to sftp-server ..."

The path to sftp-server is correct, and that path also exists inside my 
chroot directory.

If I try to sftp into the server using an account with a normal shell, 
it logs in fine.

Any pointers on where the problem might be?
Regards,
