Hello,
I use Cygwin 1.5.24.2 with OpenSSH_4.6p1 and OpenSSL 0.9.8e. When I
turn gssapi authentication on, the following error occurs:

ssh servername 

/cygdrive/f/home/username/.ssh/config line 6: Unsupported option
"GSSAPIAuthentication"
/cygdrive/f/home/username/.ssh/config line 7: Unsupported option
"GSSAPIDelegateCredentials"
/cygdrive/f/home/username/.ssh/config line 6: Unsupported option
"GSSAPIAuthentication"
/cygdrive/f/home/username/.ssh/config line 7: Unsupported option
"GSSAPIDelegateCredentials"

Actually OpenSSH_4.6p1 should support gssapi authentication?!

This suggests that when ssh was built, it was unable to find a suitable GSSAPI library, and so disabled Kerberos support. I'm not sure about how the Cygwin build system works, or even if you're working from their binaries, or ones that you have built yourself.

If you're using locally built binaries, the place to start looking is the config.log file, which should provide some pointers about why the GSSAPI check failed.

Cheers,

Simon.
