ExternalIdentityProviderService
The ExternalIdentityProviderService is necessary when using SSO (Single Sign-on).
XML configuration
Important note: The availability of a service depends on the license purchased and whether the service has been registered in the configuration file ./etc/factory.xml of the Service Factory (changes require server restart!). There you will also find the responsible configuration file for a service, otherwise you can also edit the configuration file of the service directly in the GUI of the service (changes require a service restart!).
For details see section SSO (Users).
