Hi All

Hi Rodney, hope all is well!

* [Tom] SAML/XMPP discussion

To summarize the email exchange between Tom and Peter (which was a
great start), Tom thinks it would be fairly easy to re-implement what
is essentially the system we discussed with Rodney a few years back.
Shibbolizing a web client would be fairly easy, and has some benefit
in a specific set of use cases. We could pursue this, as well as
continuing on the road of SAML attribute passing via XMPP in a more
generic way (which could be used from native clients). More discussion
on the topic is welcome, and I expect that Tom and Peter's email
conversation will continue when Peter is available again.

One quick, dirty, simple-ish and quick win for a "shibbolized" XMPP
client was to use Jeti <http://jeti.sourceforge.net> and java
webstart. It goes something like this

1) create a SP which once a user is authenticated creates a one- time
password and inserts it into the xmpp server database for that user and
downloads to the user a modified JNLP file with the one time password
and JID in it to the user.
2) modify the jeti application to get the one time password and JID from
the JNLP file and start up jeti pre-configured for the user with JID,
password (and other preferences?)

Thanks, we'll be discussing this as an approach now that we're starting down this path. Assuming that I can get a development VM from Internet2, I hope that we'll be able to use it as a testbed for this work. Java is not my field of expertise, but I suspect we'll be able to do something as a group...
