Atlassian Crowd

Finally, a single sign-on and user identity tool that's easy to use, administer, and integrate.

Users can come from anywhere: Active Directory, LDAP, Crowd itself, or any mix thereof. Control permissions to all your applications in one place – Atlassian, Subversion, Google Apps, or your own apps.

Centralize identity management
Users from multiple directories can be centrally managed via a single administration console. Manage application permissions in one place, from the same console.

SSO: Log in once
Single sign-on support means users authenticate once, and are automatically logged in to everything. Make life easy for your users – give them one username and password to log in to all the applications they need access to. Crowd's SSO capabilities are limited to a single domain.

Connectors to everything
Get started with connectors for Active Directory, LDAP, Sun, eDirectory, Directory Server, or create your own custom connector. Connect and manage access to your applications – Atlassian Tools, Google Apps, Apache, Subversion, and more.

Integrate your apps
Give developers one REST interface to every user and group – no need to learn LDAPv3.
Change directories without impacting your applications.
