As a user

ls -al /home shows
drwx--S---.  4 shared shared 4096 2010-02-17 16:10 shared

ls -al /home/shared shows
drwx--S---.  4 shared shared 4096 2010-02-17 16:10 shared

as root
ls -al /home shows the same

ls -al /home/shared shows
drwx--S---. 4 shared shared 4096 2010-02-17 16:10 .
drwxr-xr-x. 5 root   root   4096 2010-02-17 16:10 ..
-rw-r-Sr--. 1 shared shared   18 2009-12-11 11:51 .bash_logout
-rw-r-Sr--. 1 shared shared  176 2009-12-11 11:51 .bash_profile
-rw-r-Sr--. 1 shared shared  124 2009-12-11 11:51 .bashrc
drwxr-sr-x. 2 shared shared 4096 2009-09-24 01:22 .gnome2

I did not know that, thanks.

That's what I thought should work and what I tried to do but had little
luck getting it to work properly. Not knowing about needing to re-login
likely caused me some if not all of my issues.

Many thanks for the assistance.

If the information I have added helps with any ideas please let me know.
I'm thinking I'll undo what now seems over complicated and redo what I
did but try logging out and back in again to do my testing.
