> No authorization checks should be made when a user tries to create (mkdirs -p) an existing folder hierarchy.
> For example, if we start with _/home/hdiuser/prefix_ pre-created, and do the following operations, the results should be as shown below.
> {noformat}
> hdiuser@hn0-0d2f67:~$ sudo chown root:root prefix
> hdiuser@hn0-0d2f67:~$ sudo chmod 555 prefix
> hdiuser@hn0-0d2f67:~$ ls -l
> dr-xr-xr-x 3 root root 4096 Aug 29 08:25 prefix
> hdiuser@hn0-0d2f67:~$ mkdir -p /home
> hdiuser@hn0-0d2f67:~$ mkdir -p /home/hdiuser
> hdiuser@hn0-0d2f67:~$ mkdir -p /home/hdiuser/prefix
> hdiuser@hn0-0d2f67:~$ mkdir -p /home/hdiuser/prefix/1
> mkdir: cannot create directory â/home/hdiuser/prefix/1â: Permission denied
> The first three mkdirs succeed, because the ancestor is already present. The fourth one fails because of a permission check against the (shorter) ancestor (as compared to the path being created).
