Add manager-gui to the roles:

<user username="admin" password="admin" roles="admin,manager,manager-gui" />

And restart Tomcat.

Make sure that your XML configuration files are in use. A simple way to do this is writing an unclosed tag inside them and checking the error messages. If you don’t get any error message you’ve written in an unused XML.
