To set up SSO for a selected group of users to access external applications from Salesforce through App Launcher, UC must complete the following steps in Salesforce:
* Associate user profiles with theconnected apps. A connected app is a framework that enables an external application to integrate with Salesforce using APIs and standard protocols, such as SAML, OAuth, and OpenID Connect3. To access a connected app, usersmust have the appropriate permissions assigned to them, either through their profile or a permission set4. UC can associate user profiles with the connected apps to control which users can access which apps.
* Complete My Domain and identity provider setup. My Domain isa feature that lets UC create a custom domain name for their Salesforce org. It is required for setting up SSO with external identity providers.
An identity provider is a trusted system that authenticates users for other service providers. UC must set up an identity provider that supports SSO protocols such as SAML or OpenID Connect and configure it to communicate with Salesforce.
* Create connected apps for the external applications. UC must create connected apps for each external application that they wantto access from Salesforce through App Launcher. A connected app defines the attributes of the external application, such as its name, logo, description, and callback URL4. It also specifies the SSO protocol and settings thatare used to authenticate users and grant access tokens4.
