I'm working with an organisation that has implemented Portal for ArcGIS 10.3.1. They are using ADFS and, therefore, SAML2 technologies for authentication. This works great for logging users into the system. Now they want to create groups in Portal that 'map' to Enterprise groups, so that they do not have to manually add members to a Portal group. I know how to do this with 'Integrated Windows Authentication' (IWA), but I cannot find a way to do it with SAML2.
I have read the following page:
which hints at the fact that this can be done. My guess, though, is that this article relates to IWA. I do have Administrator rights in the Portal and so I have rights "to link built-in groups to enterprise groups" but I just cannot find the options to do it.
Any advice would be greatly appreciated.
