    Problems logging into Serv-U MFT

    doughk

      First of all, thanks in advance for any help I may receive.

      I am new to Serv-U MFT and got a problem that is baffling me.

       

      I installed Serv-U on Windows Server 2016 with IIS and FTP installed.

      Active Directory is enabled and configured on Serv-U with groups from the root of the domain down to where the users accounts reside.

      I added the listener, SFTP using SSH, added the IP Access, and created an SSH Public/Private key.

       

      On my PC, Windows 7, connected to the domain, I can launch FTP Voyager and configure a profile.

      It connects perfectly using the Private key.  It sees the home folder and lists out the Virtual Paths, which work fine.

       

      I have another PC, Windows 10.  The PC is fully patched, TLS1.0, TLS1.1 and SSL3 is disabled.  Logged into the PC with my Domain account.

      I created the Same Profile, used the same Private Key and my Domain account.

      It will not connect, keeps retrying.

      It appears to accept the fingerprint and key, but it displays, Password not accepted.

      I have tried several Domain Accounts, all within the same domain OU, and listed as a group in Serv-U.

      Below is the log from the client;

      Thank you

          You might want to create a support ticket for that as it might be a problem with software.  Although, you said it is only happening to one machine and that might indicate an environmental issue.


          Also, you might want to disable the IIS on the Serv-U Application Server as the Serv-U acts as it's own web server and IIS would only mess it up.
