Release : 14.1

Component : CA Directory


Linux, by default, has a security mechanism in place which prevents non root users to bind to privileged ports.


As per the official documentation https://docops.ca.com/ca-directory/14-1/en/installing/installing-ca-directory/linux/use-ports-1-1024 we need to add the capability for the dxserver executable

setcap cap_net_bind_service=+ep $DXHOME/bin/binary


setcap cap_net_bind_service=+ep /opt/CA/Directory/dxserver/bin/dxserver

If the above is in place, and errors related to permissions are still observed in the DSA trace log and /var/log/messages, please check whether the filesystem is mounted with nosuid, as one example.
