openid server

We've been discussing several solutions for the Single Signon problem in Drupal, and got to the conclusion that this is a really confusing topic and that there are several projects trying to achieve this goal in multiple ways, some of them work, some of them not quite.

Hello !

  My name is Jan and I'am member of Scout Associations of Polish Republic.
Half year ago we are tackle with authorization problem. We had many scattered applications, without any global authorization system. We start considering OpenID (this was the first think) but more important things was on one's plate.
  One of this most important things is implementing Drupal (what is almost done). Incidentally this is good time to back to talk about OpenID.

Is there any interest in having one or more Summer of Code students to work on this? Here at OSU we're getting some pings from potential applicants on working on OpenID 2.0 server support in D6. We'd be delighted to point some of our mentor and SoC student resources at this project. Especially adding support for AX, etc.

Thoughts?

Is anyone porting the openID server part from the 4.7-2.x branch to D6? If someone started at some point I'm interested in the code to finish it. If I ever make it to something usable should this be posted to http://drupal.org/project/openId or should a new project (http://drupal.org/project/openId_server) be started?

Here are links to various server PHP code with some notes:

PHP OpenID is intended to run on any version of PHP >= 4.1.0, although I have only tested it with PHP5 and PHP4.4 on gentoo. If you encounter problems running with other versions, please let me know. Great care has been taken to use PHP extensions when available and to provide fallback routines in case the extension is not present. These fallback routines are often slower and may not be as secure or "rock-solid". For production use of the library, I recommend installation of these extensions: gmp, mhash, curl, and tidy2. PHP OpenID does not use or require PEAR.
