The One Identity Manager REST API is an integral part of the application server. To use OAuth 2.0/OpenID Connect authentication for accessing the application server's REST API, there is support for the OAuth2.0/OpenID Connect and OAuth2.0/OpenID Connect (role-based) authentication modules.
Authentication is done using the access token provided. The first time a request is made with a new access token, a session is established with that token and the authentication module. Further accesses with the same token use the same session. The validity period of the token is checked in the process.
