My organization currently uses Jira Software and it is in the trial period for Confluence and JSM implementation. We have 140+ staff that will be using JSM; however, we are trying to limit the number of licensed users so we're treating them as customers (if I understand correctly, these types of users do not require a license in order to access the JSM portal).
We decided to implement SSO so that everyone can use their Microsoft credentials to create an account in Jira. So we have decided to implement Atlassian Access for that purpose. My question is, can we prevent staff from creating an account without SSO? This way, once a staff person leaves the org, they're no longer able to access Jira once their Microsoft credentials are revoked.
Another question - we sometimes invite external vendors outside of our org to Jira Software. Will implementing SSO-only login impact our ability to work with vendors in Jira?
