- Yes. As we will see in the following chapters, Keycloak provides a Service Provider Interface (SPI) that allows you to integrate not only with databases but with any other form of identity store.
- No. In addition to storing information from LDAP in its own database, Keycloak also caches data for entries that have been imported from LDAP. You have complete control over how information is cached and when it expires. Here, together with the synchronization settings, information from the LDAP directory is periodically updated without it impacting the overall performance of the server.
- Keycloak allows you to configure mappers for identity providers. Through these mappers, you can customize how users are created by setting a specific user attribute or setting a specific role when the user authenticates for the very first time.
