Integration CAS + (Jira/Confluence) Issues

[Sabrina Lanzotti]

We are facing an issue and I will try to explain it the best that I can.
We have a working configuration using Jira with CAS for one client (in the diagram the green square), and now what we want is to integrate Confluence with Jira but using local authentication. When we test this it works from Jira to Confluence but not from Confluence to Jira. Is there a way to isolate the authentication methods? So that we can use Jira with CAS and apart Jira with Confluence using local authentication.

Does anyone been through something like this? any help you could give us? Thanks!

Perhaps it is worth trying setting up Jira as the user management device for Confluence so Jira authenticates via  CAS and Confluence authenticates via Jira? Please see Connecting Confluence to Jira applications for User Management for more information on how that would work.

Hi Ann, thanks for reply.

We already tried that but with no luck. The integration without CAS works great, but when adding the CAS config we lose all our local users integration.
