Subject RE: IBM FileNet P8 CMIS URL addressability + Daeja ViewOne Viewer
Date Thu, 28 Aug 2014 19:21:35 GMT
Just to add one salient point, HTTP cookies are part of the HTTP spec (RFC6265<http://tools.ietf.org/html/rfc6265>
is the most current). So after receiving a Set-Cookie header with the LTPA token in it, the
viewer should echo back that cookie in the Cookie header.

We support SSO today.  The SSO method that we support is the LTPA token in the http header
which is handled automatically by the Websphere container where our CMIS service is running.
This is a standard way of handling this and it seems like the viewer should support this as
well.

Do we know for certain that the viewer can not support this?

Bottom line as we ship today. For SSO to work the client needs to include that standard HTTP
header (cookie) with the LTPA token.  (or do basic HTTP auth, which again uses HTTP headers)

Putting it in the url would be non-standard (at least not part of the CMIS spec) so I am reaching
for a way to avoid this.

Hi,

Do you mean 'Would you want the client to request the *URL* with an extra
extension parameter..."?

I'll be retrieving the URL with this (straight from your book):

       if (session.getBinding().getObjectService() instanceof LinkAccess) {
           return ((LinkAccess)
session.getBinding().getObjectService()).loadContentLink(session.getRepositoryInfo()
                   .getId(), document.getId());
       }

If that URL had the token, great - if not and we had to do something extra
(like add it ourselves somehow), still OK.  The main thing is that the
repository can actually use a URL with the token in it.

Another thing occurred to me - would some kind of Single-sign on make all
this 'just work' (including the viewer)?  Apologies that I keep mentioning
the viewer, but it's the main problem here!

Thanks,

Tim
