title: TortoiseSVN not asking for authentication?
body: <p>I've setup a new SVN repository, running SVNServe, in the conf file, anon-access = none.</p>
  
  <p>SVNServe faithfully does that correctly, but when I try to browse the repos using TortoiseSVN, it just says access is not allowed. Shouldn't it ask me for the user name and password instead?</p>
  
  <p>How do I get TortoiseSVN to ask me for the login details?</p>
  
  <p>Running SVN 1.5.6, TortoiseSVN 1.5.9</p>
