no i haven't, however i mention that i think we _should_ ignore
MACHINE.SID if we choose to go ahead with the fix to sidstr code
(described below) and move to SAM.SID insead. and the contents of SAM.SID
should have its rid components in hex _without_ leading "0x"s on them.

not exactly, although this is better than a kick in the teeth.
we have a window of opportunity to not have to do a
backwards-compatibility job due to the fact that the bugs found in
string_to_sid and sid_to_String cause 82.5%, by probability, of all
current alpha and beta users, problems with joining a domain, after the
bug is fixed.
given that this is the case, we might as well fix sid_to_string and
string_to_sid to match what microsoft defines the S-1-5-... format to be,
namely that all rid components are in hex, _without_ the 0x in front.
your call, jeremy.
