Some of our external users have an Atlassian account and the Org they have access to is already SSO enabled .
We'd like to invite these users to our Org for collaboration , Is it possible to claim their domain to manage these user accounts on our side ?
I understand that for SCIM User management you need to verify their domain but not sure if this is possible in our case as their domain has already been claimed by a different Org for SSO purposes.
What would be the the best way to handle user provisioning of external users in our case .
Thank you in advance for your help .
