Auth failed error when opening files using XRootD in pyROOT

Hi Eric,

Thanks for the post.
This is not expected. I would like to ask you to perform a few tests to gather a more complete view of what is happening:

  1. Is the ROOT used via Python the same you are using in C++? (ROOT.gROOT.GetVersion())
  2. Can you build the same chain from C++?
  3. Could you set the environment variable ROOTDEBUG=1 (or 2 or higher) and go through the messages to see whether the logs reveal some issue with the authentication?
