Single Sign-On Definition

August 9, 2005

At a SunGardSCT training there was a slide with a nice, concise definition of single sign-on or SSO.

Single Sign-On:
One userid, one password, entered one time, with passage allowed from one system to another without interruption

Sometimes there is debate over the meaning of the term, I accept this definition as true, and all further references I make henceforth will be based off this.

integration, sso, single sign on, definition, identity management

    [...] When dealing with portals we all get very excited about single sign-on (SSO), but I think we often forget single sign-out or overall session management. The end user really gets the main visual benefit from SSO, so this is what I find myself concentrating on. Yet, if somehow connections to external systems are not addressed when a user logs out, you have a potential security problem. [...]

    [...] Once again, this is a nice concise definition. It’s good to have these clearly defined to eliminate any confusion or debate when discussing, similar to what I did with my “Single Sign-On Definition” post. [...]

    [...] As an addition, Plymouth State University uses CAS. Interestingly, at the moment CAS is far away the most common, although Shibboleth is gaining some ground. I’m sure this is because Shibboleth has the added benefit of being capable of federated SSO. [...]

  7. No Sheep » Shibboleth For AuthZ on June 27th, 2006 9:40 am

    [...] Until this point I had only though of Shibb as a solution for inter-organizational web-based single-sign on (Federated SSO or WebISO or WebSSO). I knew I could use Shibboleth internally to serve as my WebSSO, but we already have a hugely successful implementation of CAS in our environment. Additionally I haven’t been able to point at a killer application of the federated WebSSO ability. I knew this driver would be coming, but without immediate demand I was luke warm on Shibboleth.
