A user account can be suspended (become inactive) if it has not been used for a given amount of time. The Reset Last Authentication Time feature allows you to reactivate the user account by resetting the date and time the user last authenticated with the POST /users/{userID@domain}/reset-last-authentication-time endpoint.
The following status codes are included:
204: Last authentication time reset.
400: The input is invalid.
403: The command is prohibited for the tenant admin account.
404: User account not found.
500: Internal error, sub-service failure, server crash.
