Description

We are using keyboard interactive 2-factor authentication with Cyberduck and SFTP. We had problems before CD-2911. This was fixed and was working with 6.1.0 (25371). Latest version 6.2.11 (26765) it has stopped working.

Version 6.3.1 (27114) our OTP-authentication does not work in this version either. Our system is based on SSH keyboard-interactive prompts from a pam_radius module asking for an OTP-prompt.

Can you confirm that your server does use no password authentication but only keyboard-interactive for both password and OTP.

comment:5 Changed on Nov 21, 2017 at 3:27:07 PM by jonas_lindemann

I ran ssh -v to our server, which gave the following log: 

debug1: Next authentication method: keyboard-interactive
Password:
Enter your Pocket Pass OTP: 471410
debug1: Authentication succeeded (keyboard-interactive).

This should indicate that keyboard-interactive is used for both.

Thanks in advance!

 Thanks! That is helpful. We have a regular expression match that we default to the user password per default for .*[pP]assword:\s?\z which is why the password is sent instead of the token.

Unfortunately it doesn't work. However, I get the OTP-prompt, but the login still fails and I get a repeated OTP-prompt.

We have again refactored the login flow for SFTP authentication methods in r43439. If you could please update to the latest ​snapshot build 27155 available and test that would be much appreciated.
