My dutch is a bit rusty but this text is obvious.  And unexpected.
What was supposed to happen is this:

- LookupAccountSid returns with error
  ==> Check if the local machine knows the domain name of the SID
  ==> Yes: Create a fake group name "DOMAIN+RID"
      No:  Create a fake group name "Unknown_Group+GID"

At this point all the required information isd apparently cashed
by the local LSA.

Cache is empty again.

No, because it comes from `id', not from Cygwin, and as I wrote
above, it's in fact unexpected and unwanted.  Could you try to
strace this scenario?  Maybe I can figure out why the account name
faking didn't work.


Thanks,
Corinna
