Users who are not authorized do not get a good error message, they get a timeout instead.
When looking at https://git.ligo.org/computing/helpdesk/-/issues/3469 it looks like the user is getting is that the nds2 acls are not complete. So the user connects, provides LIGO.ORG credentials, is not authorized and the system just times out.
I verified that vincent was not in the acls on nds@LHO.
I am verifying the correct set of grouper groups.
We should give a better error message back to the user. Unknown, timeout is the wrong one.
