We use Microsoft Azure to provide authentication to many of our SaaS products in the cloud. Ideally this would be the way we have our staff authenticate to our cloud-based Jira apps like Jira, Jira Service Desk, and Confluence.
It appears that Atlassian Access is the recommended tool for doing this, but is it required? It does more than we need, so I'm guessing our CIO would rather not pay for an add-on unless it's really required.
Our goal is to provide simple SSO to Atlassian cloud apps. We will have close to 100 licensed users, and around 15,000 employees who will be Service Desk customers. Is it possible for us to just use LDAP or do we actually need to go with Atlassian Access?
