Universal Container head of IT department requested from the salesforce admin to set up users with SSO (Single Sign on) so that they can log into their Salesforce org with their company network credentials. What are the steps needed for this to be achieved? Choose three answers.

Answer options:

A.Create Federation ID for each user
B.Set up SSO settings in Salesforce
C.Set up Salesforce settings in the SSO provider
D.Set up the user as a new SSO user through setup manage users

Correct Answer: A, B, andC 
You can set up single sign-on (SSO) so that users can access Salesforce without logging in again. This mechanism is called inbound SSO. Likewise, you can set up outbound SSO so that users who are logged in to Salesforce can access third-party apps and other services without logging in again. 
Salesforce supports SSO from third-party identity providers. For SSO to work, you need an identity provider and a service provider to coordinate authentication and authorization information using SAML assertions. 
Remember what the prerequisite is for SSO? a custom domain is needed for SSO. 
Option D is incorrect because you don’t have the option to set up a user as SSO user.
