sftp authentication in dolphin

Starting with kde4, trying to connect via “sftp” to another opensuse box requires multiple authentication attempts (~3x) before finally going through. It never was a problem in kde3.

Coincidentally, I have similar issue with freenx server and NX client (kde4 on both ends). I wonder if this is related issue. Again, never had issue when using kde3.

BTW, I can ssh fine in both case.

Any help will be much appreciated.

Thanks
