Hi Andy,
thanks for explaining. Yes there is one (minor) issue: in 7.1.6 instr. tracing
logs the new password in the trace file when running “dsmc set password”
(whoops). So from a support perspective you might want it enabled, bur from a
security perspective we must disable tracing on those client levels.
