openssh unix dev - Apr 2004 - [PATCH] bsd-cygwin_util.c: Relax pubkey authentication prerequisites

Hi,

is it possible to apply the below patch before 3.8.1p1 comes out?

Due to a posting on the Cygwin mailing list it turned out, that the
prerequisites to allow public key authentication where to tight.
Since Cygwin version 1.5.x the so called `ntsec' setting isn't require
anymore to allow switching user context without password. 

The below patch to bsd-cygwin_util.c fixes the test for that.


Thanks in advance,
Corinna
