Twiki

While I don't know of anyone who has tried to use Twiki (http://twiki.org/) with Raven, a project similar to Raven from the USA reports:

A quick glance at Twiki and it doesn't look like you have to do anything special. TWiki relies on Apache for its authentication and thus if your Apache server is Shib enabled, then it should be as simple as setting up your TWiki folder to use Shib authentication instead of say htpasswd.

More info on TWiki auth is at http://twiki.org/cgi-bin/view/TWiki/TWikiUserAuthentication"

If true, Twiki should work with Raven under Apache if the mod_ucam_webauth module is used to implement authentication.
