Technical definition of SSO
Single sign-on (SSO) is a property of access control of multiple related, but independent software systems. With this property, a user logs in once and gains access to all systems without being prompted to log in again at each of them. ( From Wikipedia)
Technical example of use
SSO attributes required by Sketch Engine
To assign a SSO authenticated request to an organisation licence in Sketch Engine, attribute
eduPersonPrincipalName or attribute
eduPersonScopedAffiliation (in both cases in the form of
something@organisationID) is required. This enables the ‘anonymous account’ functionality in Sketch Engine.
To distinguish particular users within an organisation, attribute
eduPersonPrincipalName (in the form of
userID@something) or attribute
eduPersonTargetedID is required. This enables the ‘full account’ functionality in Sketch Engine.
It is sufficient to provide any unique person identifier. Personal information such as name or email address is not required at all. We can adapt to other attributes if desired.
