I am working on SOAP Proxy to SFTP receiver with PGP encryption.

While placing the file into target directory with authentication method as Private Key I am getting the below error. where as it is working if I go with Password type authentication.

error Log:

Transmitting the message to endpoint <local> using connection SOAP_http://sap.com/xi/XI/System failed, due to: com.sap.engine.interfaces.messaging.api.exception.MessagingException: javax.resource.ResourceException: java.lang.UnsupportedOperationException: received authentication request from server which could not be processed: destination=varianmd@papidadb.cis.varian.com; name=; instruction=prompt=Password:



Can you please help me with this.

    Hi Gayathri

    I faced this issue sometime back and it was because the SFTP server has keyboard interactive authentication switched on. Refer to SAP Note 1945020.

    Check with the SFTP server admin if they can turn that off.

    When I was trying to resolve this issue, I also came across SAP Note 2073667. It also mentions the same error message. You might want to check that too to see if your SFTP adapter is at the right patch level so that the jSch library is an updated one.

    Hi,

    If you are using certificate for authentication then you need to generate private and public key in your PI server have you shared this public key to the third party ?

    Gayathri,

    It could be due to FTP permission as well. Not sure it will help, but please double check.

    Hi All,

    Now the issue got resolved thanks for the inputs. Finally BASIS team has resolved the issue.

    Nothing missed from PI end. There were some security checks missed while generating the Keys.

    Thanks,

    Gayathri.
