2. OpenID is an open standard for authentication.
Model is based on confidence links between Service
Providers and Authentication Providers (i.e. OpenID
providers) to achieve Single Sign On authentication

3. OAuth is an open standard for authorization.
It provides a method for clients to access server
resources on behalf of a resource owner

4. OAuth is an open standard for authorization.
It provides a method for clients to access server
resources on behalf of a resource owner
etc...

5. Experiment
Filter access to Kalideos (i.e. SPOT) data
through a secured WMS server using OpenID
Connect (i.e. OpenID over OAuth)
