[Chin Huang] observes that Microsoft's Active Directory Services Interface (ADSI) exposes a [COM] interface, so it is accessible through such
examples as
    # List all users in the domain named "MAIN".
    package require tcom

    set domain "MAIN"
    set collection [::tcom::ref getobject "WinNT://$domain"]
    $collection -set Filter [list "User"]
    ::tcom::foreach item $collection {
        puts [$item Name]
    }

----
Also, [Franco Violi]'s [TclLDirectory] extension is said to understand
ADSI.














----
Yet another way to consider Active Directory is as an instance of
[LDAP] service.
