Issue:
A knowledge Manage cannot create a new Knowledge Category if his Tenany access is set to Contacts Tenant.
Steps:
-> Set up Multi-Tenancy and create an SP tenant, a Parent, and a few Child tenants.
-> For a user belonging to the Parent Tenant, assign the Knowledge Manager role.
-> For that role set Tenancy Settings as Contact's Tenant
-> Now log in as the Knowledge Manager user, go to Administration -> Knowledge -> Knowledge Categories
-> Right-click on the Top node. Notice that the New Category menu item is grayed out.
-> If the Tenancy Settings is changed back to All Tenants, the user can see the New Category option.
