How can you force a certain SSO on a specific Sevice Portal

[JC S_]

We are implementing multiple service portals and we need to force a specific SSO on each portal. So the end result would be when a user goes to portal A he will login using SSO A and when user goes to portal B he will login using SSO B.

Any ideas on how we can do this? We can see in service portal configuration that you can define a login page, but how can this be set to a specific SSO provider instead?

I would say that this approch works, however be carefull with having a static sys_id in the code, since if you ever needs to have updated this Down the line, it might not be so easy to remember how.

In company(core_company) and User (sys_user) table there is SSO source field available. Based on the value in this field user would be redirected to the login portal as per the configuration in IDP. Set the value in the SSO Source field in the format sso:sysid of identity provider.

In Identity Provider table you will have actual configuration for IDP.

If you update field in company table it would be applicable to users of that company.
