Hopefully this has not been fixed in a newer release - I saw no mention in the changelogs... We (CMS T2 UW-Madison) are running xrootd 4.8.0-2.osg33.el7 and have installed osg-ca-certs.noarch 1.73-1.osg33.el7 . While experimenting with letsencrypt certs, xrootd displays the following message: secgsi_GetSrvCertEnt: failed to load certificate for the issuing CA '4f06f81d.0|4a0a35c0.0' There are files with is name pointing to xrootd certs: ls -al /etc/grid-security/certificates/4f06f81d.0 lrwxrwxrwx. 1 root root 26 May 23 16:22 /etc/grid-security/certificates/4f06f81d.0 -> letsencryptauthorityx3.pem ls -al /etc/grid-security/certificates/4a0a35c0.0 lrwxrwxrwx. 1 root root 26 May 23 16:22 /etc/grid-security/certificates/4a0a35c0.0 -> letsencryptauthorityx3.pem Xrootd transfers fail mentioning "AUTH". (sorry, don't have exact message) Switching back to OSG issued certs (or InCommon) allow xrootd to function normally. Thanks! -- You are receiving this because you are subscribed to this thread.
