I created few directories for my application as "myself" but I am running
the script as a cgi.

drwx------ thomas thomas  [somwehere in the world]/test
drwx------ thomas thomas  [somwehere in the world]/test/test2

my web server and I are different users,  as "nobody" have no read/go
through access on the parent (test) directory I am checking, it can not even
try to perform any action on the child one (test2).

Nothing with the current return code indicate that the test failed.
I was just guessing : return 0 means no directory present, not enable to
perform the requested action ..
