SingleSignOn: Can we setup multiple Atlassian Cloud Instances that authenticate to the same domain?

[Jackson Lum]

Hi, we are an organization that has multiple entities sharing the same domain in active directory. Some entities want to setup Atlassian Cloud instance that is only for the use that entity. However, all these entities are interested in using Single Sign On with the same domain. From my research, Atlassian Access is needed for Single Sign On. There is a discussion on Verifying a Domain.

My question is: can we setup multiple Atlassian Cloud Instance that all authenticate using the same domain? For example, we would like to have ACME1, ACME2 and ACME3 Atlassian cloud instances, but everyone has an email address of XXX@ACME.COM.

Last time I checked to have that integration you must have access, it can't be done straight from Jira. Maybe you need to add the user there first, it's not the tool I use the most.

Any chance you are using Access to manage logins? Maybe you are trying to bring users from an active directory that clearly won't have external users
