To be more specific... On one of my current SME Servers (v7.51), I have an Ibay "classfiles" that has Write=Group Read=Everyone perms.
In a standard user's home folder, I created a symlink called "classfiles" that points to "/home/e-smith/files/ibays/classfiles/files/".
The user is then able to log into their home folder and see the folder/link "classfiles" and is able to navigate to it and see, view, and open it's contents.
On SME8, I have been unable to do this. The user sees the folder/link, but when they try to access it, it gives an Access Denied error.
