This release has enhancements for the HTTP Access Method which connects to SAS in an Viya deployment. Prior to this release, only user/pw authentication was available. But there is a different mechanism for connecting in a SSO (Single Sign On) configurations of Viya. This requires 'clients' to be defined which provide scope and authorization groupings, ... An admin creates these as part of post-deployment so that an end user can then use their credentials to acquire one time auth codes used to signon (instead of their user/pw), based upon the client_id and client_secret previously set up. There are new config definition keys for these attributes and prompting in place when necessary for the authcode if it's not provided on the SASsession() method.
