Error connection in LDAP with Activiti 6 using Active directory

[lapr1997]

I'm trying integrate Active Directoriy en Activiti 6 but I dont know how.
In the documentation on the seccion 15 say
"To add the LDAP integration code to your project, simply add the following dependency to your pom.xml"
and then add the configurations bean. But not specific it where.
In the repository from de activii https://github.com/Activiti/Activiti choosing the tag activiti-6.0.0
i tried add the dependency in the pom of activiti-ui and then in activiti-app
and the bean in activiti-context.xml, although we add "The processEngineConfiguration" with Spring no does'nt work it.

Someone has succeeded in integrating ldap and active directory?????
