I have a peculiar issue with Jira Cloud + Atlassian Access. We use SSO (to Azure AD) with automated provisioning for regular users, which works fine. Now, though, we are trying to add a few external partners to our Jira instance. They have Guest accounts in AAD, the provisioning works fine (AAD reports users are successfully created with the correct attributes), but they are not appearing in the "Users" list in Jira, and are unable to log in via our SSO.
I'm sure I'm missing something in the configuration, I just can't work out what/where!
Any pointers on where I should look? Is it more likely to be in Atlassian Access config, or Jira Core/Software?
Follow-up: could it be because I can't add the external partners email domain to "Verified Domains"? I really, really don't want to go creating accounts in our domain for these partners.
