You will need either a custom authentification module or a working "users.auth.php" 
in "dw/conf/users.auth.php". A normal dokuwiki install will generate one using the
credentials you used during the install.

To use the CVS authtentification module, an environment variable is required, its 
name is "dokuwikitoken". See the sample lighttpd.conf for an example (or use 
SetEnv in Apache).

There is no data in cvs. The data is only available on the server and backup many
times daily. If you need sample data using the production documents, please contact
the php webmaster list.
