Explanation:
From the Cisco FAQ on Cisco Aironet Wireless Security:
What steps does Open Authentication involve for a client to associate with the AP?
The client sends a probe request to the APs.
The APs send back probe responses.
The client evaluates the AP responses and selects the best AP.
The client sends an authentication request to the AP.

The AP confirms authentication and registers the client.
The client then sends an association request to the AP.
The AP confirms the association and registers the client.
