From my understanding user session info for OpenAM only can be access by Session API. And we need to use post-auth plugin to extract those info and insert to cookie.
By question is: - Without using post-auth plugin, is that a way to configure OpenAM (via UI) return specific user session attribute(s) (eg. AuthType) to it's cookie?
Thanks
OpenAM policy agents can store session attributes to cookies or headers (see realm -> access control -> Agents -> Your agent -> application).
The other option would be to use OAuth flows (Open Identity Connect) - which can present user attributes in a JWT token as part of the authentication process. Your client would have to decode the JWT token and extract the attributes.
