If you’re following OpenSSO at all, you can’t have failed to notice the recent buzz around the Fedlet – from Daniel (complete with screencast), Eve Mark D, Mark H, Tatsuo, Derrick, Marina and Daniel at Sun to Coté at RedMonk and Enrico at Tenthline.
Briefly, the ‘Fedlet’ is a package that a SAML 2.0 identity provider can create to quickly federation-enable a small service provider. The idea is that, if you’re running a single web application, you’re not going to want to deploy a whole ‘nother server to run a standalone service provider. What you want is a little package of code and configuration to federation-enable your web app. You want the Fedlet.
I’ve been wrapped up in demos and travel for the past month or so, so I haven’t had much of a chance to play with the Fedlet. Since I’m planning to demo it in my session at CommunityOne on Monday, I thought I’d better do so – I set aside this afternoon to get it working. Turns out I was a little pessimistic there – here’s what I did, in less than an hour:
- Update from OpenSSO CVS (
cvs -q update -dP
- Cleaned out previous build detritus and built the WAR file (
ant clean && ant server-war
- Deployed onto Glassfish (don't forget to change GF's
-clientJVM option to
-server, as detailed in the release notes!)
- Pointed Flock (my preferred web browser du jour) at the newly deployed OpenSSO at http://demo.example.com:8000/opensso (I alias demo.example.com to 127.0.0.1 in /etc/hosts), configured OpenSSO to use the embedded OpenDS instance for its configuration and user stores.
- Logged in as amadmin, created a SAML 2.0 identity provider and a Fedlet.
- Unzipped the Fedlet, deployed it into Glassfish.
- Ran the Federation validator to check that SSO is operational.
When you spend your time in the weeds of a project, you always half expect any given step to fail due to some issue or another. Perhaps some recent fix destabilized something; perhaps some errant process has eaten my laptop's memory; whatever. So it was extremely gratifying when all of the above passed off without a hitch. I won't tell you what I muttered under my breath as the federation validator completed and gave me the thumbs up, but the second word was "cool!"
