JSM portal-only customers SSO with Entra ID redirects to login.live.com

[Julien Béchade]

Hi,

I'm a bit puzzled. I followed this guide https://confluence.atlassian.com/cloudkb/configure-saml-single-sign-on-for-portal-only-customers-with-entra-id-formerly-known-as-azure-ad-1541081409.html to set up SSO for portal-only customers but it always redirects to https://login.live.com/oauth20_authorize.srf and not to our actual Entra ID login page.

I went over the guide many times to make sure I did not omit something or made a mistake. The request is actually reaching https://login.microsoftonline.com/{{uuid}}/saml2, the entreprise app. login URL, but is redirected to login.live.com from there so the issue is definitively in Entra ID.

Did anybody stumble upon this issue and resolved it?
