We are looking at creating multiple domains in the OpenID Connect redirect_uri.
Previously in version 4.1.1, we would be configuring in the Sector Identifier setting.
However in 4.2.2, this setting has been deprecated in favour of `Sector URI` in the OpenID Connect Client.
Documentation on this setting is lacking at this point in time, so I am not sure on how to configure this.
Currently my understanding is this `Sector URI` needs to resolve to a JSON for the sector identifier, so I have to host this JSON file somewhere accessible to Gluu, am I correct?
Also, what is the spec for the JSON file to define the sector identifer?
