Hallo Andy, even if the proxy is in the standard /tmp/x509up_u* location and X509_USER_PROXY is not set, the xrootd clients fail if X509_USER_CERT and X509_USER_KEY are set to none with the exact same error. (But this would also not work for me as i need to use the proxy certificate from an non-standard location.) Thanks, cheers, Stephan -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1831#issuecomment-1324177880 You are receiving this because you are subscribed to this thread.
