Actually, this is still a known problem for the OpenSSH sftp client. You can't
"cd", but you can still do get/put/ls operations on the full path (see below).
The fix is as I described in comment #2, but I haven't implemented it yet.

[djm at baragon djm]$ cd /tmp
[djm at baragon tmp]$ mkdir -p dir_1/dir_2/dir_3
[djm at baragon tmp]$ chmod 0755 dir_1 dir_1/dir_2/dir_3
[djm at baragon tmp]$ chmod 111 dir_1/dir_2
[djm at baragon tmp]$ sftp -S /usr/libexec/sftp-server blah
