=== Added session_state parameter to OpenID Connect Authentication Response
The OpenID Connect Session Management specification requires that the parameter `session_state` is present in the OpenID Connect Authentication Response.
In RH-SSO 7.1, we did not have this parameter, but now {project_name} adds this parameter by default, as required by the specification.
However, some OpenID Connect / OAuth2 adapters, and especially older {project_name} adapters (such as RH-SSO 7.1 and older), may have issues with this new parameter.
For example, the parameter will be always present in the browser URL after successful authentication to the client application.
If you use RH-SSO 7.1 or a legacy OAuth2 / OpenID Connect adapter, it may be useful to disable adding the `session_state` parameter to the authentication response.
This can be done for the particular client in the {project_name} admin console, in client details in the section with `OpenID Connect Compatibility Modes`,
described in <<_compatibility_with_older_adapters>>. There is the `Exclude Session State From Authentication Response` switch,
which can be turned on to prevent adding the `session_state` parameter to the Authentication Response.
If you run into an error saying that the application identifier was not found in the directory, you will have to register the client application again in the
Accordingly with LinkedIn, all developers need to migrate to version 2.0 of their APIs and OAuth 2.0. As such, we have updated
our LinkedIn Social Broker so if this integration is in use make sure you upgrade to {project_name} version 7.2.6 or later.
Existing deployments using this broker may start experiencing errors when fetching user's profile using version 2 of
LinkedIn APIs. This error may be related with the lack of permissions granted to the client application used to configure the broker
which may not be authorized to access the Profile API or request specific OAuth2 scopes during the authentication process.
Even for newly created LinkedIn client applications, you need to make sure that the client is able to request the `r_liteprofile` and
`r_emailaddress` OAuth2 scopes, at least, as well that the client application can fetch current member's profile from the `https://api.linkedin.com/v2/me` endpoint.
Due to these privacy restrictions imposed by LinkedIn in regards to access to member's information and the limited set of claims returned by the
current member's Profile API, the LinkedIn Social Broker
is now using the member's email address as the default username. That means that the `r_emailaddress` is always set when
