Login Announcement links not working for "https://[...]/servicedesk/customer/portal/1?forcesso"

[Fabian]

Hello all

I have an employee-only helpdesk instance, where all users opening the URL are being redirected to SSO via the resolution SAML app and automatically signed in with their company account - works fine ever since.

I also have a helpdesk instance, where external and internal users are collaborating. Here I disabled the automatic SSO login, to allow externals to enter their username and password. Now this causes some confusion with internal users, as they think they need to enter their domain credentials (which does not work). As a solution, I wanted to add a login notification including a link to the automated SSO login (see screenshot):

Link setup: https://<our custom jira domain>/servicedesk/customer/portal/1?forcesso

This does not work however and instead opens the same login page with the same notification in a new tab instead of actually logging the user in. If I copy/paste the link from the notification and navigate there manually, the redirect parameter works just fine - so I assume some kind of weird wrapper inside Jira as the root cause. If I put a link like www.google.com in the notification it also opens correctly in a new tab. Given the time Atlassian takes to fix bugs, does anyone know a feasible workaround for this?

Many thanks in advance!
