Kiwhan,

I see your user is a domain user, and you have at least one domain group.
You may have to do an "mkgroup -d >> /etc/group", just to pull in other
domain groups.  I'd bet that if you did "ls -ln cygcheck.txt", you'd see a
group id >10000, which indicates a domain group.
	Igor
P.S. It'd be interesting to find out why mkgroup created two entries with
the same SID, but thought that one was a domain group...  Pierre?
