Azure AD authentication


I want to connect Rancher to Azure AD. I am not that familiar with Azure and I have a question regarding the Admin account that needs to be filled in in Rancher when wanting to connect to Azure AD.

What does the admin account actually do when making the connection to Azure AD? Is it neccessary to finish something with the app registration?

With kind regards,



I recently integrated AD with rancher.
The purpose of admin account is to query active directory and list groups ,users etc.
I am not expert and maybe wrong here.
The admin account can be a service account which has got read only privileges to AD.
Hope this helps.
