Store the type of 'sec channel' that we establish to the DC. If we are a

workstation, we have to use the workstation type, if we have a BDC account,
we must use the BDC type - even if we are pretending to be a workstation
at the moment.

Also actually store and retreive the last change time, so we can do
periodic password changes again (for RPC at least).

And finally, a couple of minor fixes to 'net'.
