Thnaks for the rapid response. Overnight, I thought that it would also be nice to be able to copy "UserA" to new "UserB". If "Services" could be maintained in the same way (copying "ServiceA" to "ServiceB"), that would be good too.
Expanding this further, it would be fantastic if you could assign "Users" to "Services" (in addition to the other way round).
It would be great if "Services" could be enabled/disabled at domain level (in the same way that Users can be enabled/disabled). It might, for example, be desirable to disable FTP (even on a temporay basis).
Finally, why not add the facility to assign only certain "Services" to certain "Computers" for total flexibility.
I'll shut-up now ....
Thanks!
