                                  Azure AD login for linux and windows(on premise) In this blog I will explain how to login to your on-premise Linux and windows instances using your Azure AD credentials without any need of on-premise AD. First let us see how to do it in ubuntu: For ubuntu we will be using ADAL for nodejs for implementing this. You can get the code from the git-repo here, https://github.com/thuvarageshchiv/adal-for-linux.git  move to your home directory, $ cd ~ $ git clone https://github.com/thuvarageshchiv/adal-for-linux.git $ cd adal-for-linux/adal-auth-ubuntu/aad-login $ ./install.sh  [NAME of YOUR AZURE ACTIVE DIRECTORY] [APP CLIENT ID] Now before running the script we need details of the Azure AD name and native application client ID. To get your directory name just login to Azure active directory and switch to users and select the user for whom the access is needed. The user name has a mail ID like thuvaragesh@ example.com here example.com is your directory name.
