I have used winscp.

is it correct?

We have followed same steps...

so what is the sollution, now we need to deploy any SAP NOTE?

in note they have suggested like resolution: Switch off the Keyboard-interactive authentication on the SFTP server.

How we can switch off the same?

Hi Vishnu,

Check below SAP Note, you need to update your SFTP dapter.

2073667 - "UnsupportedOperationException" on SFTP receiver channel

Update the Software Component SFTP ADAPTER 1.0 to SP003 Patch06 or above(Available in the Referrence note).
With the new adapter version, the jSch library is upgraded. So that it can better handle the password prompt string for differrent SFTP Servers.

Regards,

Praveen.

Hi Praveen,

Why I am getting Password issue, here I am using Private key based Authentication in PI?

and any one please confirm me on the process I have followed to save SAP PI SFTP public keys in SF SFTP server is right or wrong?

And switching off the authentication should be done at the SFTP server level.
