- The initial status of the settings after installation
is:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | a1 (D, U, F) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F)
| Admin 1 | a1 (D, U, F) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F) | User | a1 (D, U, F) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F)
|
The settings visible to Admin 0, Admin 1 and User are identical:
they are the default values provided by the software.
- Admin 0 explicitly changes Setting 1 to value b1:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F) | Admin 1 | b1 (D, U, F) | a2 (D, U, F)
| a3 (D, U, F) | a4 (D, U, F)
| User | b1 (D, U, F)
| a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F)
|
Admin 1 and User inherit the value b1.
- User explicitly changes Setting 2 to value b2:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F)
| Admin 1 | b1 (D, U, F) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F) | User | b1 (D, U, F) | b2
(D, U, T) | a3 (D, U, F) | a4 (D, U, F) |
- Admin 1 explicitly changes Setting 2 to value c2 and
Setting 3 to value b3:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F) | Admin 1 | b1 (0, U, F) | c2
(D, U, T) | b3
(D, U, T) | a4 (D, U, F) | User | b1 (0, U, F) | b2
(1, U, T) | b3 (1, U, F) | a4 (D, U, F) |
When the User starts a session, because the User has not
yet explicitly modified Setting 3, the User inherits directly
the new value b3. However, as the user has already explicitly
modified Setting 2, the modification of Setting 2 made earlier
by Admin 1 is not visible.
- The User then resets the settings:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F) | Admin 1 | b1 (0, U, F) | c2
(D, U, T) | b3
(D, U, F) | a4 (D, U, F)
| User | b1 (0, U, F) | c2 (1, U, F) | b3 (1, U, F) | a4 (D, U, F)
|
After the reset, the User immediately sees that the value
of Setting 1 is imposed by Admin 0, whereas the values of Settings
2 and 3 are imposed by Admin 1. The main difference is that,
for Setting 2, the User now inherits the value c2.
- The User explicitly changes
Setting 2 to value d2 and Setting 4 to value b4:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F) | a3 (D, U, F)
| a4 (D, U, F) | Admin 1 | b1 (0, U, F) | c2
(D, U, T) | b3
(D, U, T) | a4 (D, U, F) | User | b1 (0, U, F) | d2
(1, U, T) | b3 (1, U, F) | b4
(D, U, T) |
- Admin 1 locks Settings 1 and 2:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T)
| a2 (D, U, F) | a3 (D, U, F)
| a4 (D, U, F)
| Admin 1 | b1
(0, L, F) | c2
(D, L, T) | b3
(D, U, T) | a4 (D, U, F) | User | b1
(0, 1, F) | c2
(1, 1, F) | b3 (1, U, F) | b4
(D, U, T)
|
The User now inherits the values of Settings 1 and 2 directly:
the values are locked so they cannot be modified.
Note that the value locked for the Setting 1 is directly
inherited from the Admin 0. The lock and value can be set at
different administration levels.
- Admin 1 unlocks Setting
1 and explicitly changes the value to d1:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F)
| a3 (D, U, F) | a4 (D, U, F) | Admin 1 | d1
(0, U, T)
| c2
(D, L, T) | b3
(D, U, T)
| a4 (D, U, F) | User | d1 (1, U, F) | c2
(1, 1, F) | b3 (1, U, F) | b4
(D, U, T) |
Because the User has not yet explicitly changed (and therefore
has not saved) Setting 1 before Admin 1 locked it earlier, the
User now inherits the new value d1 from Admin 1 when the setting
is unlocked.
- Admin 1 unlocks Setting
2 and explicitly changes the value to e2:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T)
| a2 (D, U, F) | a3 (D, U, F)
| a4 (D, U, F) | Admin 1 | d1
(0, U, T) | e2
(D, U, T)
| b3
(D, U, T) | a4 (D, U, F) | User | d1 (1, U, F) | d2
(1, U, T) | b3 (1, U, F) | b4
(D, U, T) |
Earlier in the scenario (Step 6),
the User had already explicitly changed the value of Setting
2 to d2 before Admin 1 locked it. This value was saved. Consequently,
because the lock is no longer present, the User does not inherit
the new value e2 from Admin 1 (as in Step 8).
In this case, once the setting has been unlocked, the User
retrieves the value set in Step 9, i.e.
d2.
- Admin 1 sets Setting1 to c1 and Setting 2 to c2 again
and locks them:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F)
| a3 (D, U, F) | a4 (D, U, F) | Admin 1 | c1
(0, L, F) | c2
(D, L, T) | b3
(D, U, T) | a4 (D, U, F) | User | c1
(0, 1, F)
| c2
(1, 1, F) | b3 (1, U, F) | b4
(D, U, T) |
- The User resets:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F) | Admin 1 | c1
(0, L, F) | c2
(D, L, T) | b3
(D, U, T) | a4 (D, U, F) | User | c1
(0, 1, F) | c2
(1, 1, F) | b3 (1, U, F) | a4 (D, U, F) |
- Admin 1 unlocks Setting 1 and explicitly changes the
value to d1, and unlocks Setting 2 and explicitly changes the value
to e2:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T)
| a2 (D, U, F) | a3 (D, U, F) | a4 (D, U, F) | Admin 1 | d1
(0, U, T) | e2
(D, U, T) | b3
(D, U, T) | a4 (D, U, F) | User | d1 (1, U, F) | e2 (1, U, F) | b3 (1, U, F) | a4 (D, U, F) |
It is important here to note the difference with
Step 9. The user reset the setting in
Step 11, and has also lost all modifications,
therefore the d2 value of the Setting 2 is lost and is not restored.
- The User now explicitly changes the values of all four
settings like this:
- Setting 1 is changed to e1
- Setting 2 is changed to f2
- Setting 3 is changed to c3
- Setting 4 is changed to b4
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | b1
(D, U, T) | a2 (D, U, F)
| a3 (D, U, F) | a4 (D, U, F) | Admin 1 | d1
(0, U, T) | e2
(D, U, T)
| b3
(D, U, T) | a4 (D, U, F) | User | e1
(1, U, T) | f2
(1, U, T) | c3
(1, U, T) | b4
(D, U, T) |
Both Admin 1 and the User now inherit the locks and values
of Settings 1 and 3, which can no longer be modified.
- Admin 0 resets:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | a1
(D, L, F) | a2 (D, U, F) | a3
(D, L, F) | a4 (D, U, F) | Admin 1 | a1
(D, 0, F) | e2
(D, U, T) | a3
(D, 0, F) | a4 (D, U, F) | User | a1
(D, 0, F) | f2
(1, U, T) | a3
(D, 0, F) | b4
(D, U, T) |
The locks are not removed by the reset, which works only
on the values. Thus the two locks on Setting1 and 2 remain unchanged.
The default value of Setting 1 is however restored.
- The User finally resets the settings:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | a1
(D, L, F) | a2 (D, U, F) | a3
(D, L, F) | a4 (D, U, F) | Admin 1 | a1
(D, 0, F) | e2
(D, U, T) | a3
(D, 0, F) | a4 (D, U, F) | User | a1
(D, 0, F) | e2
(1, U, F) | a3
(D, 0, F) | a4
(D, U, F) |
The value of Setting 2 is now e2, and the value of Setting
4 is now back to a4.
- Admin 1 sets Setting 4 to b4:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | a1
(D, L, F) | a2 (D, U, F) | a3
(D, L, F) | a4 (D, U, F) | Admin 1 | a1
(D, 0, F) | e2
(D, U, T) | a3
(D, 0, F) | b4
(D, U, T)
| User | a1
(D, 0, F) | e2
(1, U, F) | a3
(D, 0, F) | a4
(1, U, F)
|
- Admin 0 sets Setting 4 to c4:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | a1
(D, L, F) | a2 (D, U, F) | a3
(D, L, F) | c4
(D, U, T) | Admin 1 | a1
(D, 0, F) | e2
(D, U, T) | a3
(D, 0, F) | b4
(0, U, T) | User | a1
(D, 0, F) | e2
(1, U, F) | a3
(D, 0, F) | a4
(1, U, F)
|
- Admin 0 locks Setting 4:
Setting
/Level
| Setting 1 | Setting 2 | Setting 3 | Setting 4 |
---|
Default | a1
| a2 | a3 | a4 | Admin 0 | a1
(D, L, F) | a2 (D, U, F) | a3
(D, L, F) | c4
(D, L, T) | Admin 1 | a1
(D, 0, F) | e2
(D, U, T) | a3
(D, 0, F) | c4
(0, 0, F) | User | a1
(D, 0, F) | e2
(1, U, F) | a3
(D, 0, F) | c4
(0, 0, F) |
