PowerBroker Open is an open source community project sponsored by BeyondTrust Software. The PowerBroker Open project (formerly known as Likewise Open) was launched in December, 2007. Since that time over 100,000 organizations in both the public and private sector have used PowerBroker Open for core Active Directory authentication for Linux, UNIX, and Mac systems by joining them to Active Directory domains.

PowerBroker Identity Services – Open Edition.

The first module of the PowerBroker Open project is PowerBroker Identity Services, or PBIS. PBIS is a complete, clean room, ground-up, Windows-compatible implementation based on a modern architecture. We provide a modular, programmatic, solution that pays particular attention to clarity, extensibility and usability. This allows ISVs to easily incorporate our solution. The market reception to PowerBroker Open has been overwhelmingly positive.

PowerBroker Identity Services uses Pluggable Authentication Modules (PAM) and Name Service Switch (NSS). It supports Kerberos, NTLM, and SPNEGO authentication.

PowerBroker Open is available under a GPL/LGPL v2 license or with a commercial license.


  • Joins Linux, UNIX, and Mac OS systems to Active Directory in a single step via a GUI tool or from the command line.
  • Authenticates users with a single username and password on Windows and non-Windows systems.
  • Enforces password polices across Windows and non-Windows systems.
  • Caches credentials so if you lose network access or the domain controller is down, you keep working.
