Detailed Description

Class ilRbacAdmin Core functions for role based access control.

Creation and maintenance of Relations. The main relations of Rbac are user <-> role (UR) assignment relation and the permission <-> role (PR) assignment relation. This class contains methods to 'create' and 'delete' instances of the (UR) relation e.g.: assignUser(), deassignUser() Required methods for the PR relation are grantPermission(), revokePermission()

Member Function Documentation

◆ adjustMovedObjectPermissions()

ilRbacAdmin::adjustMovedObjectPermissions	(	int	$ref_id,
		int	$old_parent
	)

Adjust permissions of moved objects.

Delete permissions of parent roles that do not exist in new context
Delete role templates of parent roles that do not exist in new context
Add permissions for parent roles that did not exist in old context

2023-08-15 sk: We need to switch off the cache here, as otherwise there seems to be no way to get an adequate reading of the new path. We switch it back on again at the end of this function.

We switch the cache back on again. See above.
