Hi Brian,
I managed to reproduce the problem: the file is read but for some
reason the cache is not
really updated (0 entries updated); this sounds like a bug. I will
try to understand whether
there is any work around to re-starting the server.
By default the client should not cache anything; it does cache the
relevant info if you set
the env XrdSecPWDAUTOLOG to 1 . You can check the client cache by
running
xrdpwdadmin -m netrc
Cheers, Gerri
PS: what version of XROOTD are you running?
