In the Apollo moon missions when the LEM returned to the CSM, which astronaut performed the docking procedure? Did the command module pilot just hold a fixed position while the astronaut flying the LEM performed the the docking or was it the other way around?

Also, I had heard that it was the mission commander that flew the LEM and the "Lunar Module Pilot" was just a title given to the second astronaut in the LEM. Is this true? I'm sure that both were capable of flying the mission but did the second astronaut ever get a chance to fly during the mission?
