What can cause a security role's permissions to be grayed out (uneditable)?

When a security role is a child of a parent role, the permissions can be inherited from that parent role. This inheritance system is designed to manage permissions efficiently by allowing specific user roles to derive their access rights from broader, overarching roles. If the child role inherits permissions from the parent, those inherited permissions may be grayed out and uneditable in the user interface. This is because the system prevents conflict or redundancy—ensuring that the child role cannot alter its inherited settings and is forced to comply with the structure established by the parent role.

In the context of the other options, inadequate privileges would typically restrict a user from viewing or editing roles entirely, rather than causing the permissions to be grayed out specifically. The locking of roles for editing would apply to scenarios where modifications are restricted, but it is distinct from the mechanism of inherited permissions. Deprecation of permissions generally refers to the removal of an access level from the role, rather than affecting visibility or editability within the structure of role hierarchies.
