I am attempting to log in to a remote SFTP site using WinSCPnet.dll from a windows service using the LocalSystem account. The log in fails with a "Password authentication failed" error. If I use the same parameters with the GUI the log in succeeds. Below is the code snippet I'm using to setup the Session Options.

With SessionOptions
.Protocol = Protocol.Sftp
.HostName = ""
.UserName = "healthpro"
.Password = "*****"
.SshHostKeyFingerprint = "ssh-rsa 2048 66:fb:7a:3d:8c:07:f0:ef:b0:89:d8:f5:92:0a:3e:c4"
End With
I suppressed the password but they are the same for both tests. I attached a file showing the logs for the GUI and windows sessions. I noticed the windows session is missing

Any help you can give on this will be greatly appreciated.

It looks like there are lot of spaces as the end of hostname (where it probably does not matter) and username (where it matters):


. Host name:        (Port: 22)
. User name: healthpro            (Password: Yes, Key file: No)
. Looking up host "       "
! Using username "healthpro           ".

Any idea where these come from?

Can you attach a complete log file from .NET assembly?
