enterprise platforms  

BELLEVUE, Wash. - March 25, 2008 - Likewise® Software, formerly Centeris, a leader in delivering
authentication and audit solutions for mixed networks, today announced the availability of Likewise
Open Spring '08, an Open Source offering that provides fast and easy integration of Linux, UNIX and
Mac systems with Microsoft's Active Directory. This release brings the platforms supported by
Likewise Open from a few to over 110 Linux, UNIX and Mac Platforms, or virtually all non-Windows
enterprise platforms. Likewise Open Spring '08 is available today as a free download from
http://www.likewisesoftware.com/download/index.php

Originally released in December 2007, Likewise Open provides organizations with a proven enterprise
solution for authentication with Active Directory. Likewise Open alleviates a number of challenges
that today's organizations have with authentication across multiple platforms.  Next month Likewise
Open will start being distributed through major Linux technology partners, including Novell
(openSUSE), Red Hat (RHEL), and Canonical (Ubuntu). 

 "With the support of the open source community, Likewise Open continues to evolve extremely fast,"
said Barry Crist, CEO of Likewise Software. "Users have been asking for more platforms and today we
are pleased to answer their requests within weeks with the additional support of Macintosh, UNIX
and all the enterprise Linux flavors. Admins can now manage authentication through Microsoft Active
Directory on virtually any machine."

"Very few organizations are running one operating system exclusively across their network. Likewise
makes authentication of non-Windows systems to AD easily installable and freely available," said
Richard Seibt, past CEO of SuSE Linux AG, and the latest addition to the Likewise Software board of
directors. Seibt was appointed President of Novell EMEA after the acquisition of SuSE by Novell in
2004. He currently serves as Chairman of the Open Source Meets Business conference organized by
Heise Media. "With all of the major Linux providers including Likewise Open in their upcoming
distros", Seibt continued. " Likewise Open is fast becoming the defacto solution for secure
authentication of UNIX, Linux and Mac systems with AD."
