I was doing a little playing around with permissions on a 5.3 box in the office and wanted to make it so that it does not take root permission to delete a users home directory once they are deactivated or deleted in smit.
the default permissions are 755 with bin as both user and group
I noticed that if i change the permissions to 775 and give a typical user group membership in bin he can not delete a file in that folder.
I noticed also that if i change the group ownership of the directory to staff, (which my user also has membership) folders contained inside I can delete.
is there something special about the bin group that would prevent even a user who has group membership from being able to take advantage of them when bin is the group owner of the folder?
