Now that google supports using thier profiles as OpenIDs, that can be used
directly to sign into ikiwiki. Just use, for example,
http://www.google.com/profiles/joeyhess . Tested and it works. --[[Joey]]
This seems to work fine if you use the profile directly as an OpenID. It doesn't seem to work with delegation. From that I can see, this is a deliberate decision by Google for security reasons. See the response here. -- [[Will]]
historical discussion
when I login via to this wiki (or ours) via Google's OpenID, I get this error:
Error: OpenID failure: no_identity_server: The provided URL doesn't declare its OpenID identity server.
Any idea how to fix this??
Google is doing things with openid that are not in the spec
and it's not clear to me that they intend regular openid to work at all.
What is your google openid URL so I can take a look at the data they are
providing? --[[Joey]]

I've debugged this some and filed
https://rt.cpan.org/Ticket/Display.html?id=48728 on the Openid perl
module. It's a pretty easy fix, so I hope upstream will fix it quickly.

A little more information here: I'm using that same openid provider at the moment. Note that
that provider isn't google - it is someone using the google API to authenticate. I normally have it
set up as a redirect from my home page (which means I can change providers easily).
<link rel="openid.server" href="http://openid-provider.appspot.com/will.uther">
<link rel="openid.delegate" href="http://openid-provider.appspot.com/will.uther">
In that mode it works (I used it to log in to make this edit). However, when I try the openid
URL directly, it doesn't work. I think there is something weird with re-direction. I hope this
isn't a more general security hole.

So, while the above bug will probably get fixed sooner or later,
the best approach for those of you needing a google openid now is
to use gmail.
Just a note that someone has apparently figured out how to use a google
openid, and not a third-party provider either, to edit this site.
The openid is
https://www.google.com/accounts/o8/id?id=AItOawltlTwUCL_Fr1siQn94GV65-XwQH5XSku4
(what a mouthfull!), and I don't know who that is or how to use it since it
points to a fairly useless xml document, rather than a web page. --[[Joey]]
That string is what's received via the discovery protocol. The user logging in with a Google account is not supposed to write that when logging in, but rather https://www.google.com/accounts/o8/id. The OpenID client library will accept that and redirect the user to a sign in page, which will return that string as the OpenID. It's not really usable as an identifier for edits and whatnots, but an alternative would be to use the attribute exchange extension to get the email address and display that. See http://code.google.com/apis/accounts/docs/OpenID.html#Parameters.
Yahoo's OpenID implementation works alike, but I haven't looked at it as much. It uses https://me.yahoo.com/ to receive the endpoint.
I've added buttons that submit the two above URLs for logging in with a Google and Yahoo OpenID, respectively, to my locally changed OpenID login plugin.
Using the Google profile page as the OpenID is really orthogonal to the above. --[[kaol]]
First, I don't accept that the openid google returns from their
generic signin url has to be so freaking ugly. For contrast,
look at the openid you log in as if you use the yahoo url.
https://me.yahoo.com/joeyhess#35f22. Nice and clean, now
munged by ikiwiki to "joeyhess [me.yahoo.com]".
Displaying email addresses is not really an option, because ikiwiki
can't leak user email addresses like that. Displaying nicknames or
usernames is, see [[todo/Separate_OpenIDs_and_usernames]].
It would probably be good if the openid plugin could be configured with
a list of generic openid urls, so it can add quick login buttons using
those urls.
The ugly google url will still be exposed here and there where
a unique user id is needed. That can be avoided by not using the generic
https://www.google.com/accounts/o8/id, but instead your own profile
like http://www.google.com/profiles/joeyhess. --[[Joey]]
