Active Directory Application Mode (ADAM)

For organizations that require flexible support for directory-enabled applications, Microsoft has developed ADAM, which is an LDAP directory service that runs as a user service, rather than as a system service.

  • Active Directory Application Mode (ADAM) is a part of Microsoft’s fully integrated directory services available with Windows Server 2003, and is built specifically to address directory-enabled application scenarios. ADAM runs as a non-operating-system service, and, as such, it does not require deployment on a domain controller. Running as a non-operating-system service means that multiple instances of ADAM can run concurrently on a single server, and each instance can be configured independently.

    Active Directory Application Mode represents a breakthrough in directory services technology that provides flexibility, and helps organizations avoid increased infrastructure costs.

    Service Pack 1
    Service Pack 1 for ADAM is now available. The package listed here is the integrated package which directly installs ADAM Service Pack 1 for new installations and upgrades existing ADAM installations to Service Pack 1. Note that ADAM Service Pack 1 is not available for Itanium-based systems.

    ADAM now ships as a part of the Microsoft® Windows® Server 2003 R2 release and can be installed through Optional Component Manager. This download is for use on Microsoft® Windows® Server 2003 systems that do not have the Microsoft® Windows® Server 2003 R2 refresh. ADAM SP1 includes the enhancements made to ADAM in the Microsoft® Windows® Server 2003 R2 release.
