How to generate XML metadata file for SAML SSO 2.0 configuration ?

[Eddy Fras]

Trying to implement SAML SSO 2.0 on Jira DC 8.5 / Confluence DC 7.4, my IDP asks me for a XML metadata file that contains a X509 certificate used to decrypt or confirm the signing, they can't register Jira/Confluence in their tool without this metadata file.

The only information I have for them are the 2 URLs "Assertion Consumer Service URL" and "Audience URL (Entity ID)" shown in SSO 2.0 configuration panel.

How do I generate such a metadata file ?

Hi Eddy,

this Question is slightly word in the Atlassian Access area (since that is a Cloud Service).

However, going to your Question about metadata on SAML for DC - the SAML that Atlassian Datacenter supports out of the box does not generate any metadata. 
So you would have to do this setup manually on your IdP and not via metadata

Just for reference here are the Atlassian Docs about configuring SAML: https://confluence.atlassian.com/enterprise/saml-single-sign-on-for-atlassian-data-center-applications-857050705.html

However to my knowledge Authentication request, signing/encryption is also not supported by Atlassian. So if this is a requirement, then you can't use the basic SAML integration form DC.

In that case (or if you need a setup via metadata), you'll have to consider a 3rd Party Plugin like ours: https://marketplace.atlassian.com/search?query=saml%20resolution%20gmbh 
Our plugins are the most installed & best rated one's in the Atlassian Marketplace - beside many other additional features we also fully support:

- Setup via metadata (both ways)
- Signed authentication requests.
- Encrypted authentication requests.

If that's a consideration then let me know which Identity Provider you are trying to integrate with - for many we do have step-by-step guide on our documentation (https://wiki.resolution.de/doc/saml-sso/latest/jira/setup-guides-for-saml-sso). Or you just book a free Screenshare with us & we help you do the setup via https://resolution.de/go/calendly

Cheers,
Chris

P.S. Full disclosure, I work for resolution, a marketplace vendor.

Thanks Chris for your answer.

Finally, my IDP accepted my homemade xml metadata file (built with an online tool available at https://www.samltool.com/sp_metadata.php), just containing both URLs provided by Jira, the X509 certificate was optional.

So no need for an additional plugin on my side, sorry for your company and good news for mine :)
