But you don't need to `su' to get that. You can simply _be_ root in
terms of POSIX. For example your NT domain\username is "FOO\earnie",
you are member of Administrators (SID: S-1-5-32-544) and your SID is
S-1-5-21-12345678-56789012-34567890-1002.

If you are using "ntsec" you can set your /etc/passwd entry that way:

root::0:0:U-FOO\earnie,S-1-5-21-12345678-56789012-34567890-1002:/home/root:/bin/bash

and in /etc/group:

root:S-1-5-32-544:0:

and voila, your Cygwin uid is 0 and gid is 0 as well and all POSIX tools
recognize you as `root', member of group `root'.

Yes, you're right. su acts as in UNIX. As I mentioned in the related
thread in the cygwin mailing list su lacks _real_ porting.
