FTPs connection failed - error ".. certificate rejected by ChainVerifier"


I wanna use the XI-File/FTP-Adapter to connect to our FTPs-Server.

We have to use Username/Password to connect to the FTPs-Server (it's an Ipswitch WS_FTP-Server) - using X.509 is not possible (it's another department administrating the FTPs-Server).

Now I get the error "Error: Message processing failed: Server

certificate rejected by ChainVerifier".

The Crypto-Package is installed and is working - we tested it by connecting via https to SAP NetWeaver.

Do we need a certificate if we just use USER/PASSWORD-Connection (no X.509)?

Thanx a lot,

Hi Wolfgang,

You need to make sure that your FTPs client ( XI ? ) trusts your FTPs server certificate ( in parallel with your authentication username/password )

This means that you need to import the CA hierarchy of your FTPs server certificate into the list of trusted CA's in XI ( either on J2EE side in the keystore service or in ABAP side via transaction STRUST , depending on where your client is ).
