Description
According to the RFC 6749 an application (client) owns the credentials and uses them to get an access token from the Authorization Server.
Authentication happens in a single request-response conversation when the request contains client credentials, grant_type (client_credentials) and optionally scope.
The response contains an access token, its type and expiration. Refresh token should not be included.
There are two main use cases for Client Credentials Grant in SSO:
Single application use case: token grants access to the application itself;
Authorized access use case: token grants access to a number of server applications according to the service user rights (group membership, authentication method allowed for service user account).
Single application use case
Description
In a single application use case a token grants access to only application itself. There is no authorization for this case.
