backup appliance 2.6.0.3 and altnames file

Today i went to setup a new backup domain using a 2.6.0.3 appliance and when i went to configure the altnames files and couldn't elevate to root.

I can't seem to access anything to modify it from either from the NetBackup CLI or the menus. I haven't read all the new document so i could be looking for a solution that is already available, but the following link no longer works from i believe 2.6.0.2 on so it should probalby be noted or removed.
