Reactivate an authorized user

Reactivates the user identified by the user_id path parameter.

New users are active from the start, so you only need this for a user who was deactivated with Deactivate an authorized user, or locked out automatically after too many failed login attempts.

Activation is identity-specific. If the user belongs to several identities, it applies only to the identity the caller represents and leaves their status on the others untouched.
