[ale] proftpd & symbolic links

[lost.sync]

Hello.

I'm pretty new to GNU/Linux and am really enjoying my experience.  Also,  
first time poster, so I hope this isn't too basic or whatever.

Essentially, I wanted to share some files with a friend of mine via ftp  
(proftpd).  I set him up an account and created a symbolic link to the  
directory containing the files I wanted him to have access to within his  
home directory.  The server itself is working great and doing exactly what  
I want except that if he issues a CDUP, it takes him to the parent of the  
linked folder, not back to his home folder.  Is there some way to make it  
bounce him (and all other users) back to ~ when they leave a linked  
directory?

Thank you,

J. Morris
