OpenID Implementation

Basics:

• cgi-bin/LJ/OpenID.pm
• cgi-bin/LJ/OpenID/Cache.pm
• htdocs/openid/*
• create_view_yadis in cgi-bin/ljfeed.pl

Consumer

This is the part of OpenID that lets users from other sites log into Dreamwidth and maintain an OpenID account.

• cgi-bin/LJ/OpenID.pm
• htdocs/openid/login.bml

Server

This is the part of the OpenID implementation that lets Dreamwidth users log into other sites using OpenID.

• htdocs/openid/server.bml

Database

• Database Table: identitymap
• Database Table: openid_trust
• Database Table: openid_endpoint
• Database Table: openid_external

YADIS

This is a file that other OpenID consumers use when trying to detect our OpenID server when our users are logging into their servers.

• create_view_yadis in cgi-bin/ljfeed.pl

Requirements

This ability requires the Perl OpenID module, supporting 2.0, such as version 1.02. (The default version in Ubuntu 8.04, 0.13, is not sufficient.)

TODO LIST

• Add canonical identifiers and local identifiers; make it so renamed accounts don't get access to previous OpenID sign ins
• Add the ability for people to attach OpenIDs to their account and manage them
• Add the ability to merge an OpenID account into a Dreamwidth account or upgrade using an invite code
