The last time Xrdadler32.cc was changed was three years ago...

I just tried with 4.11.1 on both client and server side, and I don't see it outputing three tokens. It is still two. I will try 4.11.2 and let you know.

    Hi Patrick,
    
    Aha! Something chnaged with xrdadler and it is now returning three tokens 
    instead of two. The server sends enverything but the client expectes only 
    two tokens and complains if it receives less or more. Hence the error. 
    Wei, what changed?
