Ways to set up SAML authentication

[Gauri Kaner]

There are two ways to set up SAML authentication:

(1) How to register IdP in Multi-Provider SSO-> Identity Providers.
→ Probably the function originally used when registering multiple IdPs.
Register ADFS as an IdP here and set it to use that IdP.

(2) How to register IdP information in SAML 2 Single Sign-on-> Properties.
→ Probably the function used when registering only one IdP.
Register ADFS information here.

The ServiceNow product document "ADFS integration with SAML 2.0" contains the method (2),
In the case of unofficial information on the Internet, method (1) is often introduced.

<What I want to know>
For the requirement of SAML authentication in ADFS
I want to know if there are advantages and disadvantages of each ①and ②.

I think that ① is more versatile and easier to do.
Since the product document contains the method ②, is there any harm in method ①?
