This exists in my httpd.conf file:

<Location /svn>

   DAV svn
   SVNParentPath /Users/iirp/Sites/svn
   Allow from all
   #AuthType Basic
   #AuthName "Subversion repository"
   #AuthUserFile /Users/iirp/Sites/svn-auth-file
   #Require valid-user

</Location>

This is working file

When I change this to:

<Location /svn>

   DAV svn
   SVNParentPath /Users/iirp/Sites/svn
   #Allow from all
   AuthType Basic
   AuthName "Subversion repository"
   AuthUserFile /Users/iirp/Sites/svn-auth-file
   Require valid-user

</Location>

and when I access my repository through URL, it gives me the authentication screen but after that screen my svn repository is not showing up correctly.

to see message that it gives to me is:
