[OpenAFS] To read a file from a directory whose ACL is r-l (read permission but no lookup permission)

[acemi]

Hello,

I want that users can't browse the directory's content (files list) but 
they can open/read a file if they know the name of the file. To do that 
I set r-l (read permission but no lookup permision) as ACL, but user 
can't read the file in this case.

I googled to learn how I can do but I can't find a solution. Is there a 
way to do that?


If no, to hack some part of source code will be a solution? Which parts?
is "viced/afsfileprocs.c" the file which I need to hack?
