EdLUG Talk - An Introduction to OpenID
On Thursday 01 November I gave a brief talk titled “An Introduction to OpenID” at the monthly EdLUG meeting. The slides for the talk are available on Slideshare. It seemed to go well despite my fear of public speaking. A few questions were put to me; some of which I could answer.
The few I couldn’t answer were mainly regarding the specifics of the OpenID authentication process. Perhaps it was nerves, but in hindsight I realise I knew the answer all along. I was asked if OpenID could tie into Kerberos or PAM. This is really down to how one chooses to implement the standard.
The OpenID specifications state that at at some point authentication must be performed with the Identity Provider. However, the details of how this authentication must be performed are purposefully not specified and instead left up to the implementor. So in answer to the questions, yes you can use Kerberos or PAM in the authentication process, but it’s up to you to tie it all together. In fact, traditional username/password combinations need not be used. If one so chooses secure fobs or biometrics could indeed be used; it’s up to you!
