How are you creating your MD5 hashes? Something like the following works well in Java:

MessageDigest messageDigest = MessageDigest.getInstance("MD5");  
messageDigest.update(user.getPassword().getBytes(),0, user.getPassword().length());  
String hashedPass = new BigInteger(1,messageDigest.digest()).toString(16);  
if (hashedPass.length() < 32) {
   hashedPass = "0" + hashedPass; 
}

When you encode "koala" do you get "a564de63c2d0da68cf47586ee05984d7"?
