Sharing Base
Allow to share objects between organizations so they can be seen by users with silos
ITSM Designer
PHP 8.1

This extension allow to share objects between organizations, enabling access to them, despite silos created by Allowed organizations on Users.


The purpose of sharing “a Document X belonging to organization A, with an organization B”, is to allow users which can only see Documents belonging to organization B to see also this Document X, even if it is not in the scope of Documents he should normally be able to see.

  • Classes of objects which can be shared is defined in XML by a to-be-created extension or an XML injection
  • Objects are shared between organizations individually.
  • Objects can be shared with multiple organizations
  • When an object X belonging to organization A is shared with organization B, it can be modified by any user who has Write-access on this object class for organization A.
  • User having organization B but not A within his “Allowed Organizations”, even if he has write access on the class of object X, will not have write access to that object, as it does not belong to one of his “Allowed Organizations”.
