Realms API

Realms are used to authenticate users across several different user access control systems.

There are two types of realms currently supported: native, which uses Fusion itself to manage users and passwords, and LDAP, which uses an LDAP server as the source of truth for usernames and passwords.

Authenticating users with an LDAP system creates a user record in Fusion, which includes a property for the realm the user belongs to. This Fusion user record is used by administrators to grant users access permissions for the UI or REST API services.
