In the world of posix conformity, permissions are typically defined by user/group/all
In omv when setting permissions on a share the reference is administrator/user/others.
For clarity, does 'administrator' line up with 'user', 'user' with 'group', and 'others' with 'all'? It is a bit confusing and am just assuming that this is the case however I have been bit in the 'ass'uming before.
