Since migrating to SSO new users are no longer added to our jira-users and confluence-users groups. Instead, users are added to groups synced from our idp. We have replicated global permissions, jira permission schemes and space permissions and added the groups to product access but it is not possible to switch default access groups from the product permissions admin page. The option is not available and the tooltip says: "this is a read only group and cannot be set as default" so I have two questions:
1. Is it possible to change default access groups to a synced group and if so how?
2. Given that permissions and access is aligned with the default access groups, what difference does it make to change default access group? (bearing in mind that new users aren't automatically added to the group by our idp)
