Hello Afaust.
Thanks for your quick response. But I have a new problem.
I set the property:
<property name="createMissingPeople">
<value>false</value>
</property>
In authentication-services-context.xml and now when I try to create a new user get the error:
Unable to create authentication as there is no suitable authentication service.
org.alfresco.repo.security.authentication.AuthenticationException: 04140015 Unable to create authentication as there is no suitable authentication service.
at org.alfresco.repo.security.authentication.AbstractChainingAuthenticationService.createAuthentication(AbstractChainingAuthenticationService.java:66)
Thank's.
