Additional info:
The SVN repository is running on a Windows server. The following is from an Apache httpd.conf file:
<Location /svn>
   DAV svn
   SVNParentPath C:/svn/repositories

   # our access control policy
   AuthzSVNAccessFile C:/svn/conf/users-access-file.txt
   
   #try anonymous access first, resort to real
   #authentication if necessary.
