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.
