RUCIO authentication does not work on AL9 for now
Please use SL7 if you need to use rucio
normal tokens (below) for xroot access do work
Make certain you have al9 set up
Then use htgettoken to get a token so you can read the files you find.
htgettoken -i dune --vaultserver htvaultprod.fnal.gov #:8200
export BEARER_TOKEN_FILE=/run/user/`id -u`/bt_u`id -u`
The first time you do it it will ask you to authenticate using a web browser.
You should be able to read files at remote sites now.
You may need to repeat the htgettoken as the interactive tokens are pretty short-lived. Batch jobs do their own tokens.
