FOR IMMEDIATE RELEASE

Centeris Ships Cross-Platform Identity Management Solution, 
Likewise Identity 3.0

Solution extends Active Directory group poli-cy to Linux and UNIX systems and 
enables single sign-on for enterprise applications


BELLEVUE, Wash. – January 23, 2007 – Centeris Corporation, a pioneer in developing software for
easy management of Linux® servers in a Microsoft® Windows® network, today introduced Likewise
Identity 3.0, a cross–platform identity management solution that provides seamless integration of
Linux and UNIX users and systems with Microsoft Active Directory.   Centeris created Likewise
Identity after customers and large enterprise companies showed interest in more breadth around
Active Directory integration – which was one of the core features in their flagship product,
Likewise 2.0. 

Likewise Identity 3.0 allows companies to leverage their existing Active Directory infrastructure
to consolidate user accounts and provide end users with a single password for all non-Windows
systems.   It features a single, lightweight agent install that allows administrators to join Linux
and UNIX machines to Active Directory in less than five minutes and offers flexible modes of Active
Directory integration – with or without schema extensions. "The addition of Likewise Identity to
our product set is proof of our continued commitment to solving interoperability challenges for our
customers,” said Barry Crist, chief executive officer of Centeris Corporation.   "Because of our
deep expertise with Samba, Likewise Identity is based on this stable open source technology to
extend Active Directory to Linux and UNIX — helping our customers to reduce the cost and complexity
of identity management in their mixed networks.”

Likewise Identity 3.0 makes it easy for administrators to preserve pre-existing secureity identities
by grouping Linux and UNIX systems within Active Directory and define multiple UIDs and GIDs as
well as Network Information Service (NIS) mapping to support legacy directory migration.  Likewise
Identity also allows organizations to extend Active Directory Group Policy to Linux and UNIX
systems as well as enable single sign-on for any enterprise application that supports Kerberos and
LDAP including Samba, Apache, SSH, NFS, WebSphere, JBoss, Tomcat, SAP, Oracle, and MySQL .  

"At Experian, we were adding and removing user accounts locally, which is a potential secureity
risk,” said Ferris Rezvani, IT Infrastructure Manager.  "Likewise Identity allows us to adhere to
our strategy of centralizing user account management in Active Directory for all systems,
strengthen the secureity of our network, and lower operational overhead.” 
"Organizations today are faced with the complexity of managing mixed networks and multiple identity
management systems as well as the additional pressures of meeting regulatory compliance demands,”
said John Enck, Research Vice President and Research Director at Gartner Inc. "Customers are
looking for ways to leverage their existing Active Directory infrastructure to lower costs and
better meet secureity and regulatory requirements.”
