Default Idp and Primary Idp use in multi provider sso

[sachin312]

We recently upgraded to Multi Provider SSO from SAML 2. No issues users are redirected as they were while using SAML 2.

1. I created second Identity provider to support proxy server as mentioned in this article https://hi.service-now.com/kb_view.do?sysparm_article=KB0621579 . I made default as false on both identity providers and updated "glide.authenticate.sso.redirect.idp" value with two identity provider sysId's.

(Requirement) When user access:

https://ourinstance.service-now.com   --> they must login in using first Identity provider

https://ourcustominstance.com --> they must login in using second Identity provider

(Issue) When user access:  

https://ourinstance.service-now.com   --> they are redirected to service now login in page

https://ourcustominstance.com --> they are redirected to service now login in page

Note: I know we can use external login link first time so that glide_sso_id value is stored in browse cookie. But we don't want this to happen to users.

2. What is difference between default idp and Primary idp? https://docs.servicenow.com/bundle/helsinki-servicenow-platform/page/integrate/single-sign-on/task/t...

How to configure default idp and primary idp, when using Multiple Identity Providers??
