Hi,
Yes we tried. Our setup is something like this. User is authenticated using
a kerberos ticket. We initially used "exec" channel. Since the users of
that server, only has rssh accessibility, we moved to "sftp" instead of
"exec". Even with that, we I try to execute a command (like pwd()), I'm
getting the following error.
