enables you to use a centralised identity to login to any website that supports OpenID. It opens up the possibilities of massive scale cross-domain SSO.
Think about all the accounts you have online: blogs, wikis, to-do lists, photo galleries. The list is endless. Even simple tasks such as leaving comments on someone else's blog may require you to register an account with that particular blogging system. This leaves you, as an end user, to set up and manage numerous accounts on each of these sites. With OpenID, rather than managing all these disparate accounts individually, users can manage their identity in one place via an authentication server.
With the ever-increasing adoption of this open authentication framework, including names such as Microsoft, AOL, Sun, Verisign and Firefox, expect to see many applications enabled for OpenID authentication.
CrowdID offers OpenID to an organisation's user base, allowing users to manage their online identity. Everything from configuring different profiles, managing trusted sites to reviewing authentication activity, is accessible from CrowdID. Administrators can set up whitelists/blacklists so that only trusted hosts can request authentication and can set up secure communication via SSL. All of the users can be managed via Crowd's security server, utilizing LDAP services from products such as Microsoft Active Directory.
Included with CrowdID is a sample OpenID client application, providing a working example of an OpenID enabled application. This will help developers kick start OpenID-enabling their applications.
