NETBEANS - Apache Tomcat 8.0.3.0 - can't access the /manager direcotry

Are you trying to access /manager and you can't?
You already changed the file tomcat-users.xml but still you can access the manager?
The problem is that there two places where you can find tomcat-users.xml

I changed the file in the directory Catalina Base and it worked.
Maybe, like me, you changed tomcat-users.xml of the directory that is in Program Files.
Hope it helps!
