5 [http://openid.net/ OpenID] is an decentralized authentication mechanism for the Web. mod_openid turns Prosody into an OpenID _provider_, allowing users to use their Prosody credentials to authenticate with various third party websites.

9 mod_openid can best be described as a *proof-of-concept*, it has known deficiencies and should *not* be used in the wild as a legitimate OpenID provider. mod_openid was developed using the Prosody 0.4.x series, it has not been tested with the 0.5.x or later series.

13 OpenID works on the basis of a user proving to a third-party they wish to authenticate with, an OpenID _relaying party_, that they have claim or ownership over a URL, known as an OpenID _identifier_. mod_openid uses Prosody's built in HTTP server to provide every user with an OpenID identifier of the form `http://host.domain.tld[:port]/openid/user`, which would be the OpenID identifier of the user with a Jabber ID of `user@host.domain.tld`.

17 Simply add "mod_openid" to your modules_enabled list. You may then use the OpenID identifier form as described above as your OpenID identifier. The port Prosody's HTTP server will listen on is currently set as 5280, meaning the full OpenID identifier of the user `romeo@montague.lit` would be `http://montague.lit:5280/openid/romeo`.

35 * It is important that the OpenID key-value responses be signed in the proper order so that the signature can be properly verified by the receiving party. This may be complicated by the fact that the iterative ordering of keys in a Lua table is not guaranteed for non-integer keys.
