UserIdentityInfo
class UserIdentityInfo
Contains information about the identity of a user.
For Connect Customer instances that are created with the EXISTING_DIRECTORY identity management type, FirstName, LastName, and Email cannot be updated from within Connect Customer because they are managed by the directory.
The FirstName and LastName length constraints below apply only to instances using SAML for identity management. If you are using Connect Customer for identity management, the length constraints are 1-255 for FirstName, and 1-256 for LastName.
