There is evidence that password-less logins (as well as exim) fail
on Windows 2003 because the SYSTEM account is lacking the CreateToken
privilege and can't setuid(). I don't know if/how that privilege can be
added, can you investigate?
A workaround (reported to work) is to create a new privileged account and
to run the daemons under that account (-u switch in cygrunsrv).
The new account (you could call it Root) should
1) be in the Administrators group
2) have the Login As A Service privilege
3) " Create Token "
4) " Assign Token "
5) " Increase Quota " (if it exists on your system. Does it?).
In addition by being Administrators it should also have the Backup and
Restore Files privileges. If not, assign them explicitly.
Rebuild /etc/passwd after creating such an account.
