This topic provides an overview of Single Sign‑On for VMware Tanzu Application Service.
Single Sign‑On is an all-in-one solution for securing access to apps and APIs on VMware Tanzu Application Service for VMs. Single Sign‑On provides support for native authentication, federated single sign-on, and authorization. Operators can configure native authentication and federated single sign-on, for example SAML, to verify the identities of application users. After authentication, Single Sign‑On uses OAuth 2.0 to secure resources or APIs.
Single Sign‑On enables users to log in through a single sign-on service and access other apps that are hosted or protected by the service. This improves security and productivity by removing the need for users to log in to individual apps.
Developers are responsible for selecting the authentication method for application users. They can select native authentication provided by the User Account and Authentication (UAA) or external identity providers. UAA is an open source identity server project under the Cloud Foundry (CF) foundation that provides identity based security for apps and APIs.
Single Sign‑On supports service provider-initiated authentication flow and single logout. It does not support identity provider-initiated authentication flow. All Single Sign‑On communication takes place over SSL.
After authentication, Single Sign‑On uses OAuth 2.0 for authorization. OAuth 2.0 is an authorization framework that delegates access to apps to access resources on behalf of a resource owner.
Developers define resources required by an application bound to a Single Sign‑On service instance and administrators grant resource permissions. See the Configuring Applications topic for more details.
