my business unit is migrating from Confluence server (which is connected to our AD and allows our small subset of users to use Confluence) to the Confluence Cloud. I've been able to migrate the data, but now I'm working to set up SSO. I have a few questions as I'm in a small business unit in a very large organization...
I know I have to verify the domain first and I have to work with my IT staff to get that done (using Azure AD methodology). Then I subscribe to Atlassian Access tool. My question is that we're purchasing 100 user licenses (adding more than our current 25 licenses) to expand our use. Our AD probably has 10k+ users...how do I ensure that only the 100 users I want get the access to our Confluence Cloud system.
