Thanks.  It's not helpful, unfortunately.  The only hint that something
is going wrong is the same message as with chmod:

  internal_getlogin: group not found in group DB

There's no other strace message even remotely related to account mapping.
I don't grok that.  There should really be some error message :(

Btw., what's the output of `id'?

I'm wondering... is it possible that LDAP access to your DCs is
restricted?=20=20

Also, can you change /etc/nsswitch.conf like this:

  db_enum: cache local primary

(see https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-mapping-nsswitch-enu=
m)

exit and restart your shell and call `getent group'?  What does it
print?  Are the AD accounts enumerated and what info is printed for
them?  Examples are sufficent, I don't need your entire AD DB :)

Also, what does `getent passwd $USER' print?
