Guidance for SSO/SAML setup with Azure IDP / Entra for many products/sites

Boris Ning

Hi,

I'm interested in setting up SSO/SAML with Azure AD/Entra as the identity provider. I've read through two guides and a youtube video on how to set it up, but I'm confused about some initial steps.

- Microsoft:

https://learn.microsoft.com/en-us/entra/identity/saas-apps/atlassian-cloud-tutorial

- Atlassian Guide:

https://support.atlassian.com/security-and-access-policies/docs/configure-saml-single-sign-on-with-an-identity-provider/

 

As an Atlassian org admin, I have a number of Atlassian Jira / Confluence sites (separate subdomain on atlassian.net) as well as hundreds of unmanaged users. This is where I have a lot of questions in the ordering of the setup:

To setup SSO/SAML, should I first claiming some of the unmanaged users to become managed users and use those subset of users as trial? Eventually all of those users will need to be managed (under the same domain) to use SSO/SAML, right?

When setting up SSO/SAML, how do I set it up for multiple sites with multiple subdomains? Should I add multiple Azure Enterprise Application to handle each site? or is there a way to incorporate multiple sites onto a single Enterprise Application?

 

Thank you,

-Boris

Hi @Boris Ning ,

To setup SSO/SAML, should I first claiming some of the unmanaged users to become managed users and use those subset of users as trial?

When testing an SSO setup, you can shortlist a few users and add them in the Azure application that will govern the login. Managed/Un-managed users won't matter for this use case.

From what I've tested, after you've claimed a domain, new users are auto added to your managed users, so the need to manually claim them might not be needed (unless you've setup the Claiming to be manual). This doesn't impact the SSO signin though.

When setting up SSO/SAML, how do I set it up for multiple sites with multiple subdomains?

SSO is applied to a certain Domain, I haven't checked/Seen the option to apply it to just one site yet.

IMHO, I would recommend getting in touch with the Atlassian Support team for a demo, and discussing this with their team directly. SSO/SAML when well understood can be applied easily, but since we don't have a limited Sandbox to test this out, the impact may hamper your existing users too.
