Departments are Imagen Roles that existbeneath an Imagen Organisation (one organisation to many departments). Specific SSO attributes can bemapped to a Department, and Departments can be associated with Imagen Groups,making it possible to configure ACLs per Department

The following attributesare the most important:○urn:oid: must be aunique ID that very rarely changes (i.e. this is a user ID). If it ever changes, seethe User account merging point below. This is arequiredattribute.○urn:oid:0.9.2342.19200300.100.1.3(mail): The user’semail address. This isused to pre-populate the user’s registration form when theyfirstvisit ImagenWeb.The user can opt to use a different email address if so desired.●

User account merging

If the user’s eduPersonTargetedIDever changes, ImagenWebwill see them as a new user and treat them accordingly. If a user wishes to regainaccess to their previous account/use their previous email address, they will need tomerge their accounts. The previous email address will be sent a message containing alink that initiates the merge and transfers the previous user’s content (collections, etc)before ultimately deleting the previous account

A federation is a collection of IDPs.If you add a Federation toImagenWeb, it’s a quick way of trusting dozens of IDPs at the same time. In Imagen’scase, we subscribed to a Federation containing dozens of UK universities, which each have their own ways of authenticating users. An organisation can be created which is linked to an IDP derived from a Federation
