We want to be able to set up SSO access for multiple users from multiple companies each to have access to their own service desks within Jira portal.
We're reading this and associated pages: Configure SAML single sign-on for portal-only customers | Atlassian Support
Does this mean we have to run our own ADFS server for all our customers, or how can we let them use their own MS login to join our service desk?
Do we somehow need to sync everyone in all external customers into our JIRA directory?
Can we have multiple external federated auth. providers?
Or how do we do it please?
