You don't. If you want to change name for display purposes, look into nsswitch.conf and associated documentation. Cygwin do not invent its own users/groups/ids/guids. It maps Windows permissions to some POSIX equivalent, but internally it still using native permissions. > I tried setfacl -x group:oldname:rwx -m group:curname:rwx but got: > setfacl: illegal acl entries Seems like it did not recognize the group name.

It should, but I strongly suggest to avoid using it outside Cygwin directory tree to maintain maximum interoperability with Windows programs. > How do you add a new user to the access list -- obviously -x removes > a user, but not sure if 'add' is covered by -m or whether or not you 'add' > by specifying the new entry. I just found out that if you configure cygdrive with noacl, getfacl tell you to find better ways to express yourself. And setfacl will silently fail (which is questionable behavior, TBH). > BTW -- is there an easy way to see the numeric values it is using > for a given name? > Like: > group:Local account and member of Administrators group:rwx getent passwd getent group > I remember seeing that, but it isn't in my /etc/group file.
