title: Spring cloud config server sends spring security login form instead of logback.xml
body: <p>I am using spring cloud config server to store <code>logback.xml</code> configuration.
  Here's my consuming microservice (the one which is spring cloud config client) <code>bootstrap.properties</code> file:</p>
  
  <pre><code>server.port=5555
  spring.application.name=test-ms
  spring.profiles.active=development
  spring.cloud.config.uri=http://localhost:8888
  spring.cloud.config.username=root
  spring.cloud.config.password=123123
  logging.config=http://localhost:8888/test-ms/development/master/logback.xml
  </code></pre>
  
  <p>This worked fine until I turned on spring security on my spring cloud config server. After that it sends
  spring security login form instead of <code>logback.xml</code> so I'm getting an exception:</p>
  
  <pre><code>Logging system failed to initialize using configuration from 'http://localhost:8888/test-ms/development/master/logback.xml'
  java.lang.IllegalStateException: Could not initialize Logback logging from http://localhost:8888/test-ms/development/master/logback.xml
  </code></pre>
  
  <p>...</p>
  
  <pre><code>Caused by: org.xml.sax.SAXParseException; systemId: http://localhost:8888/test-ms/development/master/logback.xml; lineNumber: 11; columnNumber: 5; The element type "link" must be terminated by the matching end-tag "&lt;/link&gt;".
  </code></pre>
  
  <p>because as I said it is getting spring security login page instead of <code>logback.xml</code>.
  But I need to have authentication on my spring cloud config server. 
  I tries to put user and password into url: <code>logging.config=http://user:passwordlocalhost:8888/test-ms/development/master/logback.xml</code> but it didn't help.
  How can I point my spring cloud config client to xml on spring cloud config server?</p>
