Thanks Andy. Yes, i understand but in case the proxy certificate is expired xrootd triggers a grid-proxy-init i want to avoid, thus me setting X509_USER_CERT and X509_USER_KEY to none. The issue is the xrootd client failing with valid proxy in case X509_USER_CERT and X509_USER_KEY are set to none. - Stephan -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1831#issuecomment-1324397885 You are receiving this because you commented.
