title: Spring logging threshold not being set by logback
body: <p>I am working with Spring (Core/Security/ldap and more), and logback.
  But for some reason spring does not receive the loggin threshhold set in the logback XML
  I can see that as well when i debug springs source code and i see that the </p>
  
  <pre><code>final boolean debug = logger.isDebugEnabled();
  </code></pre>
  
  <p>Is false</p>
  
  <p>As well i would like to mention (I don't know if it has any relevance) that the logger that spring uses is:</p>
  
  <pre><code>org.apache.commons.logging.LogFactory
  org.apache.commons.logging.Log
  </code></pre>
  
  <p>And not SLF4j like i use</p>
  
  <p>So how am i supposed to enable the debug level and bring the logs into my SLF4J configuration..</p>
  
  <p>Thanks</p>
