Allow blind parent directories

Description

One of the features of a unix permission system is that
you can set the execute permission on a directory to
allow a user to 'cd' through the directory without being
able to read the directory. This means you have to
know the path where you want to go. The advantage is
that users (especially if they don't know our directory
structure) are unable to 'browse' through our directory
tree.

Most FTP clients I have used allow for this feature by
allowing us to set up a site profile for a user that takes
them directly to the directory they need to access.
They are either unable to 'cd' up (..) to the parent
directory, or if they are able, once there they see
nothing.

When I try to access one of these directories using
FileZilla, even though it is able to read the directory I
want, it fails because it can't read the parent directory.
In fact, it appears to need read access for the parent
directories all the way to '/'.

I would like to be able to see a remote directory which I
have access to even if I do not have read access to the
directories above it.

An example on our system is the
directory /datatel/live/collive/_HOLD_. The directory
permissions are:

drwxr-xr-x /
drwxrwx--x /datatel
drwxrwx--x /datatel/live
drwxrwx--x /datatel/live/collive
drwxrwxr-x /datatel/live/collive/_HOLD_

Users should be able to retrive files from the _HOLD_
directory, but should not be able to get a directory
listing from any level above that.

Thanks

Don
