=== OpenID ===
Contributors: willnorris, factoryjoe
Tags: openid, authentication, login, comments
Requires at least: 2.8
Tested up to: 2.8.5
Stable tag: 3.3.4
Allows WordPress to provide and consumer OpenIDs for authentication of users and comments.
== Description ==
OpenID is an [open standard][] that allows users to authenticate to websites
without having to create a new password. This plugin allows users to login to
their local WordPress account using an OpenID, as well as enabling commenters
to leave authenticated comments with OpenID. The plugin also includes an OpenID
provider, enabling users to login to OpenID-enabled sites using their
own personal WordPress account. [XRDS-Simple][] is required for the OpenID
Provider and some features of the OpenID Consumer.
Developer documention, which includes all of the public methods and hooks for
integrating with and extending the plugin, can be found [here][dev-doc].
[open standard]: http://openid.net/
[XRDS-Simple]: http://wordpress.org/extend/plugins/xrds-simple/
[dev-doc]: http://wiki.diso-project.org/wordpress-openid-api
== Installation ==
This plugin follows the [standard WordPress installation method][]:
1. Upload the `openid` folder to the `/wp-content/plugins/` directory
1. Activate the plugin through the 'Plugins' menu in WordPress
1. Configure the plugin through the 'OpenID' section of the 'Options' menu
[standard WordPress installation method]: http://codex.wordpress.org/Managing_Plugins#Installing_Plugins
== Frequently Asked Questions ==
= Why do I get blank screens when I activate the plugin? =
In some cases the plugin may have problems if not enough memory has been
allocated to PHP. Try ensuring that the PHP memory\_limit is at least 8MB
(limits of 64MB are not uncommon).
= Why don't `https` OpenIDs work? =
SSL certificate problems creep up when working with some OpenID providers
(namely MyOpenID). This is typically due to an outdated CA cert bundle being
used by libcurl. An explanation of the problem and a couple of solutions
can be found [here][libcurl].
[libcurl]: http://lists.openidenabled.com/pipermail/dev/2007-August/000784.html
= Why do I get the error "Invalid openid.mode '<No mode set>'"? =
There are actually a couple of reasons that can cause this, but it seems one of
the more common causes is a conflict with certain mod_security rules. See
[this blog post][ioni2] for instructions on how to resolve this issue.
[ioni2]: http://ioni2.com/2009/wordpress-openid-login-failed-invalid-openid-mode-no-mode-set-solved-for-both-wordpress-and-drupal/
= How do I use SSL for OpenID transactions? =
First, be aware that this only works in WordPress 2.6 and up. Make sure you've
turned on SSL in WordPress by [defining either of the following][wp-ssl]
globals as "true" in your `wp-config.php` file:
- FORCE\_SSL\_LOGIN
- FORCE\_SSL\_ADMIN
Then, also define the following global as "true" in your `wp-config.php` file:
- OPENID\_SSL
Be aware that you will almost certainly have trouble with this if you are not
using a certificate purchased from a well-known certificate authority.
[wp-ssl]: http://codex.wordpress.org/Administration_Over_SSL
= How do I get help if I have a problem? =
Please direct support questions to the "Plugins and Hacks" section of the
[WordPress.org Support Forum][]. Just make sure and include the tag 'openid'
so that I'll see your post. Additionally, you can file a bug
report at <http://code.google.com/p/diso/issues/list>.
[WordPress.org Support Forum]: http://wordpress.org/support/
== Screenshots ==
1. Commentors can use their OpenID when leaving a comment
2. Users can login with their OpenID in place of a traditional username and password
3. Users authorized to use the OpenID Provider can delegate to a different provider
4. Users can add additional OpenIDs which they can use to login to WordPress
5. Users authorized to use the OpenID Provider can monitor which sites they've logged in to
