Anonymous access to Liferay's SVN servers now require inputting a username of "guest" with no password. We had to make this change due to some weird bugs with SVN.
That means the command
svn co svn://svn.liferay.com/repos/public/portal/trunk
will not work, but the command
svn co svn://svn.liferay.com/repos/public/portal/trunk --username guest
will work.
Access via http://svn.liferay.com/repos/public/portal/trunk also requires inputting a username of "guest" with no password.
