-== User federation mapper SPI
-
-=== LDAP mapper
-
-For the more advanced use cases, you have the possibility to create your own implementation of LDAP mapper or just subclass from some already existing mapper
-implementation. You will need to implement `UserFederationMapperFactory` interface.
-
-In most cases, instead of creating `UserFederationMapperFactory` from scratch, you can create subclasses of `AbstractLDAPFederationMapperFactory`, which itself
-implements `UserFederationMapperFactory`.
-
-Then you need to create mapper implementation, which will be subclass of `AbstractLDAPFederationMapper` (this mapper implementation will be returned by
-`YourAbstractLDAPFederationMapperFactorySubclass.createMapper` method).
-
-For details on how to package and deploy a custom provider refer to the <<providers.adoc#providers,Service Provider Interfaces>> chapter.
