HFS path testing to ensure the environment can support an increase in USS activity.
Release : 16.0
Access to the group of the final directory and the file itself is required.
The only time access to all the groups, for each directory, is when you are chaining up the directories.
for example: file /u/user/lastdir/file.
chaining up the directories..
cd /u
ls -E
cd user
ls -E
cd lastdir
ls -E
obrowse file
You would need the group permission for each directory
if you just did
cd /u/user/lastdir
obrowse file
you would get permission from lastdir and file permissions.
