I was using mkpasswd. But I have solved my problem (sort of) It came from reading these two posts http://www.cygwin.com/ml/cygwin/2006-07/msg00587.html Which led to bin/ssh-host-config and http://www.cygwin.com/ml/cygwin/2006-07/msg00588.html editrights -a SeAssignPrimaryTokenPrivilege -u username editrights -a SeCreateTokenPrivilege -u username editrights -a SeTcbPrivilege -u username editrights -a SeServiceLogonRight -u username editrights -a SeCreateGlobalPrivilege -u username editrights -l -u $1 Then login from the user specified as username to any other ordinary user works.
