Definitions of permission states
For each role, you can specify which of the pre-defined permissions are granted, not granted, or denied.
These states have the following meanings.
*
Granted - indicated with a green checkmark . Explicitly grants permission to perform this particular function as long as none of the user's other roles explicitly denies permission.
*
Denied - indicated with a red "X" . Explicitly denies permission to perform this particular function, regardless of any other of the user's roles which might grant permission.
*
Not Granted - indicated with a shaded gray "X" . Does not explicitly grant nor deny permission to perform a particular function. If this permission is not explicitly granted by any of a user's roles, the user is not allowed to perform this function.
