We are trying to add extend storage to our HCP cluster. We use AWS with ADFS policy's. Instead of having access Key's and Secret Key's we use ADFS to authenticate. Depending what AD group the user has been assign to will depend on what AWS access they have. So create a user that has access to create an S3 bucket. Now I'm trying to confiure HCP extend storage with AWS STS Authentication for ADFS. Has any one done extend storage using AWS policy's and ADFS?
