What's a "Single Sign-On"?

The answer to "Will I be able to Single Sign On with Yadis?" is not clear. Several ideas go by that name, which one do we mean here? I haven't been able to find standard, unambiguous names for these distinctions, but here's what I mean (along with some names I've made up on the spur of the moment):

  1. The user presents the same "name-like string" to any of several sites to achieve login (single identity)
  2. The user presents the single identity to any of these sites and also the same "password-like string" to prove their identity (single credentials)
  3. The user presents the single credentials to any one of the cooperating sites, and then no longer needs to present any credentials at all to access other cooperating sites (single sign-on)

Does yadis intend to support all of these use cases? It appears only to support the first two. Jackr 08:50, 7 April 2006 (PDT)


Compliance & implementation

I'd like to put in some text encouraging implementors to use full XML parsers, not regexes, and to respect and properly deal with namespaces --Danlyke 16:26, 19 May 2006 (PDT)

I'd like some clarification about when an "application/xrds+xml" MIME type is necessary (always, when content negotiation is involved, per 6.2.5 and 6.2.9) and when it's optional (it seems like any of HTTP headers or HTML meta methods would allow you to point at a file type of "text/plain" or "text/html" and say "treat this as though it was application/xrds+xml". This latter assumption may be necessary for, for instance, people at the mercy of system administrators who won't update the MIME types on their Apache installations. --Danlyke 16:27, 19 May 2006 (PDT)
