PRESS RELEASE

SANTA CLARA, Calif. -- April 22, 2009 -- Sun Microsystems, Inc. (NASDAQ: JAVA) today announced expanded interoperability between the Sun Identity Management Suite and MySQL(TM), the world's most popular open source database, allowing customers to radically reduce the total cost of ownership (TCO) for deploying identity management solutions. In addition, the new integration helps to enable companies to create more dynamic identity architectures, comprised of powerful directory services and relational databases, to improve performance and simplify management of large-scale applications.

Today's announcement was made at the seventh annual MySQL Conference & Expo (http://www.mysqlconf.com) being held this week at the Santa Clara Convention Center. With more than 2,000 attendees, it is the world's largest community event for open source database developers, DBAs, vendors and corporate IT managers.

With MySQL and the Sun Identity Management Suite, customers now have a highly flexible, scalable and efficient approach to manage their identity data infrastructure across their organization, regardless of whether they are using an LDAP directory or relational database. The Sun Identity Management Suite is the most proven identity infrastructure in the world, with more than 5,000 deployments worldwide and Sun's MySQL database provides the back-end foundation for some of the world's largest online applications. A key product in the Sun Identity Management Suite, Sun(TM) Directory Server Enterprise Edition is the market leading LDAP directory server, with more than four billion entries in use today.

"Companies continue to struggle with basic identity infrastructure issues and are looking for pragmatic approaches to simplify deployment, reduce complexity and cost while planning for future business growth," said Mark Herring, vice president, MySQL and Software Infrastructure marketing at Sun. "The combination of Sun's open source and commercial solutions along with MySQL provides the lowest TCO of any vendor in the market " allowing customers to consolidate their infrastructure, reduce expensive licensing fees, reduce time-to-acquisition and increase time-to-value."

"Identity management over the years has been making the promise to consolidate, bind together and manage identity information, and Sun Microsystems has an extensive identity management offering that does exactly that," said Felix Gaehtgens, Senior Analyst from Kuppinger-Cole. "Sun's added support for MySQL with their entire identity stack takes this to a new level by allowing organizations to bind together data regardless of whether it is stored in an classic directory or relational database."

New integration of Sun OpenDS(TM) Standard Edition with the latest release of MySQLCluster 7.0, (announced yesterday at the MySQL Conference - http://www.sun.com/aboutsun/pr/2009-04/sunflash.20090421.2.xml) can be deployed as a clustered gateway to combine the mission-critical strength of MySQL's high availability database technology with the flexibility and compatibility of the OpenDS LDAP v3 directory standard. This solution set offers some of the best performance of any combined LDAP and database solution with proven large scale deployments in large telecommunications operations. By maintaining data in standard SQL and LDAP formats, the combined solution requires no application changes and provides organizations with a simpler programming and administration model.

Sun's Virtual Directory, a key component of Sun Directory Server Enterprise Edition, provides customers with a consolidated view of identity information across all of their directories and databases. When building a new Web application based on MySQL, developers now have a simple and intuitive way to onboard new data repositories into their identity infrastructure in a standards-based manner (i.e.--LDAP v3). This standards-based approach reduces quality assurance testing, eliminates integration costs and makes identity data rapidly accessible.

In addition, Sun(TM) Identity Manager can provision users to any repository including LDAP v3 compliant directories and relational databases, such as the MySQL Enterprise(TM) Server, and can also employ MySQL as its data repository. Sun(TM) Role Manager can also be used with MySQL as its identity warehouse. Sun OpenSSO Enterprise allows customers to choose MySQL, Sun Directory Server Enterprise Edition, OpenDS Standard Edition and most third-party LDAP V3 directories as an identity repository. This allows an organization to remove security concerns from the developer so that they focus on rapid application development, and provides a common security model that can be leveraged across an organization's users, roles and resources.
