title: org.springframework.security.config package is missing
body: <p>I am building a web app with spring security and following along with a tutorial, but have ran in to a road block because the package <code>org.springframework.security.config</code> seems to be missing. I am using <code>spring-core-4.1.4</code> and <code>spring-security-4.1.1</code>.</p>
  
  <p>Here are my dependencies in <code>build.gradle</code> file</p>
  
  <pre><code>dependencies {
       compile 'org.springframework.security:spring-security-web:4.1.1.RELEASE'
       compile 'org.springframework.security.kerberos:spring-security-kerberos-web:1.0.1.RELEASE'
  }
  </code></pre>
  
  <p>All of the other packages and classes I have seen in the tutorial are there, but the config package is missing.</p>
