[Dev-luatex] Anonymous HTTP access to the SVN repository does not work

Hello, according to http://foundry.supelec.fr/scm/?group_id=10, the LuaTeX sources can be checked out anonymously using http. When pointing TortoiseSVN to http://scm.foundry.supelec.fr/svn/luatex, however, the server asks for authentication. I tried using the credentials used for this mailing list, but to no avail (which is not really surprising, since the mailing list is on a completely different server). I cannot use the svn-protocol because of a company firewall; in any case, the above behaviour is some sort of configuration bug, IMO. Could it be that WebDAV is not configured for anonymous checkout? Thanks in advance, Jonathan
