I am trying to setup a CentOS 6.5 64bit server with SVN over HTTPS. Unfortunately after configuring the /etc/httpd/conf.d/subversion.conf file as follows (changed paths):

<Location /repos>
    DAV svn
    SVNParentPath /path/to/svn/repos

    # Limit write permission to list of valid users
    <LimitExcept GET PROPFIND OPTIONS REPORT>
        # Require SSL connection for password protection
        SSLRequireSSL

        AuthType Basic
        AuthName "Authorization Realm"
        AuthUserFile /path/to/passwdfile
        Require valid-user
    </LimitExcept>
</Location>

I get the following error message when restarting http:

Starting httpd: Syntax error on line 3 of /etc/httpd/conf.d/subversion.conf:
Unknown DAV provider: svn

I have triple checked that I have the mod_dav_svn package already installed:

Package mod_dav_svn-1.6.11-10.el6_5.x86_64 already installed and latest version

Is my config wrong or are there other packages I need to set up?
