Hello Carl,
What we can tell you about OAuth2 in 11.7.2 is that support is being worked on for PAS for OE's Spring Security. Spring Security will act as a Resource Server that validates the inbound OAuth2 token, and if it can be validated and user information recovered
a Client-Principal will be created and delivered to the ABL business application. The OAuth2 Resource Server support will initially cover the REST, WEB, and static-file transports. At this time no OAuth2 support is being planned for the classic REST Adapter
and AppServer.
You are free to ask additional questions, but I will only release what we know and have unit tested.
I hope that helps,
Mike Jacobs
