Implementation of Single Sign On using SAML in Salesforce - Part 2

Implementing a Single Sign-On (SSO) infrastructure enables users to sign in once and have access to all authorized resources.

On contrary to the previous post, when Salesforce doesn't work as Identity provider, this is how the Identity Provider Initiated Login and Service Provider Initiated Login works:

Identity Provider Initiated Login:

• where a user starts directly at their identity provider,
• logs in, and
• is then redirected to a landing page at the service provider;

Service Provider Initiated Login:

• where a user starts by clicking a link to the the service provider (e.g. a bookmark, mailed link, etc)
• and temporarily redirected to the identity provider for authentication,
• then returned to the link they initially requested.
