As an administrator, you can use the Windows Azure Active Directory Module for Windows PowerShell cmdlets to accomplish many Windows Azure AD tenant-based administrative tasks such as user management, domain management and for configuring single sign-on.
Windows PowerShell is a task-based command-line shell and scripting language designed for system administration. Unlike most shells, which accept and return text, Windows PowerShell is built on top of the Microsoft .NET Framework common language runtime (CLR) and the .NET Framework, and accepts and returns .NET Framework objects. Windows PowerShell introduces the concept of a cmdlet (pronounced "command-let"), a simple, single-function command-line tool built into the shell. Cmdlets have the following naming convention: a verb and noun separated by a dash (-), such as Get-Help, Get-Process, and Start-Service. Windows PowerShell includes more than one hundred basic core cmdlets.
