You can define shared settings so that they can be reused and are available in any Identity Server cluster configuration. The settings include:
Attribute sets: Sets of attributes that are exchangeable between identity and service providers.
User matching expressions: The logic of the query to the user store for identification when an assertion is received from an identity provider.
SharedSecret names: Custom shared secret names that you want to be available when configuring policies.
LDAP attributes: Custom LDAP attribute names that you want to be available when configuring policies.
This section describes the settings that can apply to any configuration.
