4 This plugin allows users to use their [OpenID](http://openid.net/) to log
7 The plugin needs the [[!cpan Net::OpenID::Consumer]] perl module.
8 Version 1.x is needed in order for OpenID v2 to work.
10 The [[!cpan LWPx::ParanoidAgent]] Perl module is strongly recommended.
11 The [[!cpan LWP]] module can also be used, but is susceptible to
12 server-side request forgery.
14 The [[!cpan Crypt::SSLeay]] Perl module is needed
15 to support users entering "https" OpenID urls.
17 This plugin is enabled by default, but can be turned off if you want to
18 only use some other form of authentication, such as [[passwordauth]].
22 These options do not normally need to be set, but can be useful in
25 * `openid_realm` can be used to control the scope of the openid request.
26 It defaults to the `cgiurl` (or `openid_cgiurl` if set); only allowing
27 ikiwiki's [[CGI]] to authenticate. If you have multiple ikiwiki instances,
28 or other things using openid on the same site, you may choose to put them
29 all in the same realm to improve the user's openid experience. It is an
30 url pattern, so can be set to eg "http://*.example.com/"
32 * `openid_cgiurl` can be used to cause a different than usual `cgiurl`
33 to be used when doing openid authentication. The `openid_cgiurl` must
34 point to an ikiwiki [[CGI]], and it will need to match the `openid_realm`
39 See [[plugins/openid/troubleshooting]] for a number of issues that may
40 need to be addressed when setting up ikiwiki to accept OpenID logins reliably.
44 This plugin does not take care of doing the "server" part of the
45 OpenID protocol, only the "client" part. In other words, it allows
46 users to login to your site through OpenID, but is not in itself an
49 It is possible, however, to use your Ikiwiki site as a delegation
50 point to another OpenID provider. For this, use the
51 [[ikiwiki/directive/meta/]] directive with the `openid` parameter.
