AM's timeline is summarized as follows:
In 2001, Sun Microsystems releases iPlanet Directory Server, Access Management Edition.
In 2003, Sun renames iPlanet Directory Server, Access Management Edition to Sun ONE Identity Server.
Later in 2003, Sun acquires Waveset.
In 2004, Sun releases Sun Java Enterprise System. Waveset Lighthouse is renamed to Sun Java System Identity Manager and Sun ONE Identity Server is renamed to Sun Java System Access Manager. Both products are included as components of Sun Java Enterprise System.
In 2005, Sun announces an open-source project, OpenSSO, based on Sun Java System Access Manager.
In 2008, Sun releases OpenSSO build 6, a community open-source version, and OpenSSO Enterprise 8.0, a commercial enterprise version.
In 2009, Sun releases OpenSSO build 7 and 8.
In January 2010, Sun was acquired by Oracle and development for the OpenSSO products were suspended as Oracle no longer planned to support the product.
In February 2010, a small group of former Sun employees founded ForgeRock to continue OpenSSO support, which was renamed to OpenAM. ForgeRock continued OpenAM's development with the following releases:
