Role objects define which users occupy particular roles, and what additional links those users see on their webtop. Role objects are stored in the Tarantella System Objects organization within the ENS organizational hierarchy.
Note You can't create or delete role objects: there are a fixed number of roles, with predefined privileges.
In Object Manager, choosing Properties for a role object shows two tabs:
For each object in the Members tab, the tree shown on the object's own Links tab shows the role object, which expands to show the webtop links granted by the role.
From the command line, use tarantella role
to define which users occupy a role
and the extra webtop links they see.
