Hi Alexander Bokovoy provided excellent answers to most of my questions on this topic See: Thread: gssproxy security, configuration and life-cycle questions on gss-proxy@xxxxxxxxxxxxxxxxxxxxxx Remaining question: Prior to RHEL-9 , in the section of the gssd man page ( under the heading CONFIGURATION FILE ... ....options that can be set on the command line can also be controlled through .... values set in the [gssd] section of /etc/nfs.conf ) there was a configuration parameter "use-gss-proxy" why was this parameter removed from the current man page, can it be re-added ? ( apparently the parameter is still functional ... if that's the case , it should not simply be removed from the documentation with no commentary ) Thanks Andy Romero Fermilab / ITD
