[Fiware-idm-ge] OAuth2 and SSO

[Antonio Tapiador del Dujo]

Dear all,

The OAuth section in the FI-WARE architecture description starts with:

"Contrary to SAML, OAuth has nothing to do with SSO."

I believe this is a misleading statement. Althrough OAuth is not 
oriented to SSO, we do implement a SSO experience using OAuth2 in the 
FI-LAB portal. Some users have asked us about this.

So, I propose removing that statement from the documentation. Also, I 
think that starting the section with a comparation between OAuth and 
SAML does not add any value.

I would change the first sentence to:

"OAuth's main focus is on ‘protected resources’ of the user that a 
consumer wishes to access."

Best regards.
