I have a problem with "sshd" where it;
   (1) won't allow users to login, users recieve the message "Read from 
socket failed: Connection reset by peer"
   (2) "sshd" terminates prematurely.

The problem I believe (though I'm not really sure) relates to the second 
final line of output from the sshd server (see below)
   "seteuid 1005: Permission denied"
I'm running Windows XP 64-bit Edition -- it's my belief that seteuid cannot 
be called from a 32-bit context?? I could be wrong?? Though 
http://cygwin.com/faq/ seems to suggest that "Cygwin can be expected to run 
on all modern 32 bit versions [including] WOW64 32 bit environment on 
released 64 bit versions of Windows". In my config I've turned off privilege 
seperate ("UsePrivilegeSeparation no") -- however this didn't make any 
difference.

Does anyone know how I can fix this problem??! (see below for output from 
"/usr/sbin/sshd -D -d -e")

Regards,
   Glenn
