Subversive Authentication error svn OPTIONS 403 Forbidden

Suddenly Eclipse started to complaint with an error like the below when I tried to update certain local svn copies:

Authentication error.
svn: OPTIONS of '/repos/reporting': 403 Forbidden (http://subversion.nestorurquiza.com)

While someone could be tempted to grant more permisions on the SVN server the reality is that from command line I did not get the same experience. Everything was working just fine from there.

To correct this I used the Subversive Update site from Eclipse Help/Install Software Menu. After an Eclipse restart I had to pick the latest 1.6 svn connector (not native) for it to work:
