This plugin allows users to use their [OpenID](http://openid.net/) to log
into the wiki.
-The plugin needs the [[cpan Net::OpenID::Consumer]] perl module. The
-[[cpan LWPx::ParanoidAgent]] perl module is used if available, for added
-security. Finally, the [[cpan Crypt::SSLeay]] perl module is needed to support
-users entering "https" OpenID urls.

+Version 1.x is needed in order for OpenID v2 to work.
-This plugin has a configuration option. You can set `--openidsignup`
-to the url of a third-party site where users can sign up for an OpenID. If
-it's set, the signin page will link to that site.

-This plugin supports the
-[myopenid.com affiliate program](http://myopenid.com/affiliate_welcome),
-which can be used to help users sign up for an OpenID and log into your
-site in a single, unified process. When you create the affiliate, specify a
-login url like `http://example.com/ikiwiki.cgi?do=continue`. Once the
-affiliate is created, set `openidsignup` to point to the affiliate's signup
-url.
+This plugin is enabled by default, but can be turned off if you want to
+only use some other form of authentication, such as [[passwordauth]].
-This plugin is included in ikiwiki, but is not enabled by default.
+## options
+
+These options do not normally need to be set, but can be useful in
+certain setups.
+
+* `openid_realm` can be used to control the scope of the openid request.
+ It defaults to the `cgiurl` (or `openid_cgiurl` if set); only allowing
+ ikiwiki's [[CGI]] to authenticate. If you have multiple ikiwiki instances,
+ or other things using openid on the same site, you may choose to put them
+ all in the same realm to improve the user's openid experience. It is an
+ url pattern, so can be set to eg "http://*.example.com/"
+
+* `openid_cgiurl` can be used to cause a different than usual `cgiurl`
+ to be used when doing openid authentication. The `openid_cgiurl` must
+ point to an ikiwiki [[CGI]], and it will need to match the `openid_realm`
+ to work.
