OpenID

This was just a quick trial...
I did not look at OpenID in any great depth!

-------------------------------------------------------------------------------
From LCA2011 conference maillist...

As to setting up their openid-server, these are the steps I performed:

> ~ $ cd /home/httpd/
> /home/httpd $ sudo mkdir openid.longlandclan.yi.org
> /home/httpd $ sudo chown stuartl:users openid.longlandclan.yi.org
> /home/httpd $ cd openid.longlandclan.yi.org
> .../openid.longlandclan.yi.org $ svn checkout http://php-yubico.googlecode.com/svn/trunk/ php-yubico
> .../openid.longlandclan.yi.org $ svn checkout http://yubico-openid-server.googlecode.com/svn/trunk/ yubico-openid-server
> .../openid.longlandclan.yi.org $ cd php-yubico
> .../php-yubico $ make
> .../php-yubico $ sudo emerge PEAR-PEAR PEAR-Console_Getopt PEAR-DB
> .../php-yubico $ sudo pear install Auth_Yubico-2.3.tgz
> .../php-yubico $ mkdir ../htdocs
> .../php-yubico $ cd ../htdocs
> .../htdocs $ mv ../yubico-openid-server/examples/server openid
> .../htdocs $ mv ../yubico-openid-server/Auth/* openid/Auth
> .../htdocs $ cd openid
> .../openid $ cat > config.php <<EOF
> # Visit http://yourserver/openid/ and configure your database
> # settings, creating any databases as required.  Paste the config
> # it gives you here.
> #
> # Go to https://api.yubico.com/get-api-key/ to get a key, then paste
> # this:
> 
> require_once 'Auth/Yubico.php';
> $yubi = &new Auth_Yubico('YourID', 'YourSecretKey');
> EOF  

You can give the one I've set up a try here:
http://openid.longlandclan.yi.org/openid/

OpenID Delegation

You can take a URL that you already own (say, one hosting your blog) and just
delegate that off to a provider of your choice. Here's an example:
http://simonwillison.net/2006/Dec/19/openid/

You can then change providers or switch to your own if you want.
