I'm sending you an email with a development version of WinSCP to the address you have used to register on this forum.
Its log should contain more information to help debugging your problem.

It does not seem to pick up the library... GSSApi authentication works with firefox and putty on the same machine. Cheers,

OK, sorry, it should have been GSSLibs, not GssLibList.

Thanks for your reply. Just to make sure, I added a new connection, exported it to a script which looks like this: 
open sftp://XXXXXX@XXXXXX/ -hostkey="ssh-rsa 2048 8e:85:93:e0:19:61:7a:0c:05:4a:b4:58:54:05:06:58" -rawsettings TryAgent=0 GSSAPIFwdTGT=1 GSSCustom="C:%5CProgram%20Files%20(x86)%5CHeimdal%5Cbin%5Cgssapi.dll"

exit

When running this from the command line, I get in the log:

So it seems that it does not even try to load the custom gssapi.dll...

Thanks for your advice,

Re: GSSLibs and GSSCustom for all connections / all users on system

Are you testing this with a new session created after you set the defaults? Or are you testing this with an old session created previously? The default settings apply to new sessions only.
Also I've understood, that your problem was about distributing the settings. Now it seems like, that you were never able to connect.

Thanks for the quick feedback. I have:

"GSSCustom"="C:\\Program Files\\Heimdal\\bin\\gssapi.dll"

I have kerberos tickets (using Heimdal kerberos), and I have checked

* Attempt GSSAPI authentication
* Allow GSSAPI credential delegation

I unchecked

* Attempt authentication using Pageant

How can I debug this further? From klist, I can see that no credentials are being acquired for the host/FQDN principal of the destination host... Thanks,

GSSLibs and GSSCustom for all connections / all users on system

Dear all,

thanks for providing this great piece of software. I read about the new GSSLibs and GSSCustom options here:

https://winscp.net/tracker/578

Now I have been banging my head against the wall trying to understand how I use these for a connection, or ideally set these as a default for all users of my system (I want all users to use a specific path to the GSSAPI library). Thanks for any insights,

Christian
