  The directory needs to exist, and needs to be owned by the UID /GID used by the RADIUS server.  And, the permissions need to be 0700

  This is all documented in the comments around the "tmp_dir" configuration in the "eap" module.

  Follow the default configuration.  Use a directory *other* than /var/run/radiusd for "tmp_dir".  Maybe raddb/run/radiusd/tls/

  And read the comments.  Read the configuration files you're editing.  All of this is documented.
