Attached. Your gut seems to be working today...
There *is* something weird here. Look at this:
151 36702 [main] chmod 5536 alloc_sd: uid 1001, gid 513, attribute
0x2190
65 36767 [main] chmod 5536 cygsid::debug_print: alloc_sd: owner SID
= S-1-5-21-3514886939-1786686319-3519756147-1001 (+)
70 36837 [main] chmod 5536 cygsid::debug_print: alloc_sd: group SID
= S-1-5-21-3514886939-1786686319-3519756147-1001 (+)
alloc_sd (the underlying function creating a security descriptor) gets
a uid 1001 and gid 513 as input, as usual. But the owner *and* group
SIDs of the file's existing security descriptor is
S-1-5-21-3514886939-1786686319-3519756147-1001, the SID of your user
account.
Why is your user account the primary group of the file, even though
your user token definitely has "None" (513) as its primary group?
How did it get there?
I don't have a clue. You're the expert. :)
The ACLs are a little different between the Microsoft Account and the
regular local account. But, if anything, it's the regular one that looks odd
to me.
Microsoft Account:
$ icacls bar
bar WIN8-VM\Chris:(R,D,WDAC,WO,WA)
Everyone:(Rc,S,RA)
NT AUTHORITY\Authenticated Users:(M)
Local account:
$ icacls foo
foo WIN8-VM\cjb:(R,D,WDAC,WO,WA)
WIN8-VM\None:(Rc,S,RA)
Everyone:(Rc,S,RA)
Why does the local account have None permissions, and not Authenticated Users?
