<Location />
        ShibRequestSetting applicationId forum
        ShibRequireSession off
        AuthType shibboleth
        Require shibboleth
</Location>
<Location /ucp.php>
        ShibRequireSession on
        ShibRequestSetting requireSession true

SoffidOnLoadScript 'index.php$' .* 20000 /etc/apache2/soffid/forum-front.js
SoffidOnLoadScript '/ucp.php$' .* 20000 /etc/apache2/soffid/forum-ucp.js
SoffidOnLoadScript '/posting.php$' .* 20000 /etc/apache2/soffid/forum-posting.js
SoffidPostData '/ucp.php\?mode=login' system=ldap account=username password=password

Now, the following scripts must be added:
