Running ActiveDirectory Module for Powershell in Lambda

While the ActiveDirectory module technically imports in PowerShell 6+, most cmdlets unfortunately require Windows so this is not currently possible

I have not tried this on Lambda, but I have used the PowerShell module https://github.com/jformacek/S.DS.P to successfully interact with ActiveDirectory from pwsh7 on Mac and Linux. It will not work on pwsh6 because of a dependency in the underlying .NET Framework in the pwsh 7.3 release.

Is it still impossible to use ActiveDirectory Tools with Lambda?

Yes, it is possible to run PowerShell scripts inside of Lambdas functions. The document [1] explain how common programming patterns and core concepts apply when you author Lambda function code in PowerShell.

Kindly refer to the document [2] that describes how to create a new IAM group and a new IAM user and then add the user to the group using the AWS Tools for PowerShell. Document [3] provides instructions to Set an Initial Password for an IAM User. This document explains the user creation with respect to IAM service.

Please refer to the document [4] which explains that, SAML support in the AWS Tools for PowerShell lets you provide your users federated access to AWS services. SAML is an XML-based, open-standard format for transmitting user authentication and authorization data between services; in particular, between an identity provider (such as Active Directory Federation Services), and a service provider (such as AWS). For more information about SAML and how it works, see SAML on Wikipedia, or SAML Technical Specifications at the Organization for the Advancement of Structured Information Standards (OASIS) website. SAML support in the AWS Tools for PowerShell is compatible with SAML 2.0.
