A trusted identity provider is basically an identity provider that supports inbound provisioning. It can be Google, Salesforce, another Identity Server, etc.
Outbound provisioning is supported via SCIM or SPML standards. There are outbound provisioning connectors for Google and Salesforce available by default in the Identity Server.

Outbound provisioning configurations can be found under identity provider configuration user interface of the Identity Server.
