SFTP adapter dual authentication

Hi,

I have a requirement to where I have to provide dual authentication, both password and private key, to log into onto an sftp server. The SAP sftp adapter only allows user name and password or user name and private key.

Has anyone had the same requirement and found a resolution?

Does anyone know if dual authentication is on the horizon for the SFTP adapter?

regards

Julian

    Hi Julian,

    Is this an option provided only by certain SFTP server or is it a general option?

    Does the private key authentication pass and then it again prompts for password?

    • Hi Vishnu,

      Long time since we have communicated.

      I have only come across duel authentication with one SFTP server and authentication method is not optional. My work around has been to change from a pull to a push scenario, where the file gets dropped onto our SFTP server instead of having to fetch the file.

      I did suggest to Sivasubramaniam Arunachalam that the adapter be enhanced; and he replied that he had raised it with the development team.

      thanks

      Julian

    Hi Julian,

    We recently understood the dual authentication method of the SFTP Server and successfully implemented the solution. The SFTP Server issue the authentication method one after the other. That is the SFTP Server first checks for the PrivateKey i.e. the "PublicKey Authentication" and the "Password" based authentication.

    You can follow this note 2028233 which supports the dual authentication for SFTP sender or receiver side.

    Regards,
    Vishnu
