PADL Releases XAD Identity Server

MELBOURNE, AUSTRALIA -- (MARKET WIRE) -- June 8, 2005 -- PADL has announced general availability of its identity server, XAD.

XAD® provides a cross-platform enterprise identity management service on Linux. It is based on open standards and does not require a proprietary server infrastructure. All popular client operating systems and authentication protocols are supported, including Kerberos, LDAP, and Windows logon. XAD is built on proven open source software, including the popular OpenLDAP directory server.

The result of three years development, XAD is the first open systems product to support single sign-on across Linux, UNIX and Windows with a zero client footprint and native functionality. Users, computers, domains, and group policies can be managed using familiar management tools. Domains and replicas can be provisioned with a single command, avoiding the complexity of individually configuring authentication, naming and directory services.

"PADL is already established as a vendor of best-of-breed directory clients for the Linux and UNIX platforms," said Luke Howard, Managing Director of PADL. "The release of XAD complements our existing products with an enterprise-class directory server and multi-platform client support."

"XAD significantly advances the state of art for Linux-based identity management in today's typically heterogeneous server environment. XAD runs on most common Linux variants and on multiple architectures, further enabling customer choice in managing today's enterprise," said IBM's Dan Frye, Vice President, IBM Linux Technology Center.

"PADL has made many great contributions to open source," said Matthew Hardin, CTO of Symas Corporation. "XAD builds on the strengths of OpenLDAP and takes a huge step forward for identity management."

Broad Platform Support

XAD supports SUSE LINUX Enterprise Server 9 for the x86, AMD64, Intel EM64T, IBM POWER, and IBM zSeries & S/390 platforms, as well as Red Hat Enterprise Linux 4 for Intel x86.

XAD supports AIX, HP-UX, Linux, Solaris, Windows NT 4.0, Windows 2000, Windows XP and Windows 2003 client operating systems. Users have a single identity when using multi-protocol fileservers such as NetApp® Data ONTAP™, or UNIX with SAMBA and NFS. Additionally, XAD includes AFS authentication and authorization services providing seamless integration with AFS and OpenAFS deployments.

Pricing and Availability

XAD is available now, and is priced at $1000 per server.
