Step 4: Login using IDP selection page (Optional)

You can configure multiple IDPs (identity providers) and give users the option to select the IDP of their choice to authenticate with.
For Example - It could be multiple AD domains belonging to different departments or multiple okta organizations.

Few usecases where customers configure multiple IDPs -

Suppose you have a product which many of your clients use and each client has their own unique IDP so you want them to SSO into your product as well using their existing IDP only. miniOrange provides a centralized way to connect with all IDPs in a very easy manner and integrate SSO into your application.
Suppose you are providing a course to many universities, each having a unique IDP like Shibboleth, ADFS, CAS, etc. You can provide single sign-on (SSO) into your course application to all these universities by integrating with all of them using a single platform provided by miniOrange.
This is the endpoint to call from your saml application -
