Works, except when Cygwin does not provide a "U-*\NAME," in the gecos 
field. This is the case for Local Service, Network Service and 
Administrators.

Tested in db-only mode with 1.7.34-001:

   $ getent passwd localservice
   localservice:*:19:19:,S-1-5-19:/:/sbin/nologin


BTW, TrustedInstaller is not found by getent:

   $ getent passwd TrustedInstaller ; echo $?
   2

   $ getent passwd 328384 ; echo $?
   2

Same result for 'group'

but:

   $ ls -l -d /cygdrive/c/Windows
   drwxrwx---+ 1 TrustedInstaller TrustedInstaller 0 Nov 15 11:08 
/cygdrive/c/Windows

   $ ls -l -n -d /cygdrive/c/Windows
   drwxrwx---+ 1 328384 328384 0 Nov 15 11:08 /cygdrive/c/Windows

  $ getent passwd S-1-5-80-956008885-...
TrustedInstaller:*:328384:328384:,S-1-5-80-956008885-...:/:/sbin/nologin


What will be the future 'official' way for the opposite Windows->Cygwin 
conversion? Some tool that uses CW_CYGNAME_FROM_WINNAME ?
