Your tent is not leaking- what you are experiencing is condensation forming on the inside of the tent due to a lack of ventilation and high humidity inside the tent and difference in temperature between the outside and inside of the tent. This can happen in any tent, even if it's not raining. The warm water vapor from one's breath and body heat can condense and form water droplets as it comes into contact with the cool tent fabric. Additionally, wet clothes or gear inside the tent create such warm water vapor. Try cracking a window, opening peak vents, removing wet items and checking to make sure rain fly guy lines and ground vents are properly secured to keep air flowing through the tent so that condensation is minimized.
