OTOH, if there *is* an official workaround which is, "use the /etc/passwd
file to chnage your username", wouldn't that be sufficient?

I understand your point, but the search problem in the Windows user DBs
as I outlined persists.

What I did a couple of weeks ago ws to change the mkpasswd tool so that
it creates the exact same passwd entries as you get when fetching them
directly from Windows.  For instance, the passwd entry generated for
my AD account inside of Cygwin will look like this:

corinna:*:1049577:1049701:Corinna Vinschen,U-VINSCHEN\corinna,S-1-5-21-2913048732-1697188782-3448811101-1001:/home/corinna:/bin/tcsh

Using the "new" mkpasswd, calling `mkpasswd -d -u corinna', I get the
exact same entry!  If I write this into /etc/passwd, I'm getting the
exact same correct uid and gid values, but I can change my username:

  $ mkpasswd -d -u corinna > /etc/passwd
  $ sed -i -e 's/^corinna:/cathy:/' /etc/passwd
  $ id
  uid=1049577(cathy) gid=1049701(vinschen) groups=1049701(vinschen),
  559(+Performance Log Users),545(+Users),[...]

That should be sufficient, shouldn't it?
