FTP/SSL Connection Problem for FTP Receiver Adapter

872 Views

Hello All,

We are trying to establish an FTPS/SSL connection with one of our customers from our XI(Unix) system, and are receive following error:

<b>iaik.security.ssl.SSLException: Server certificate rejected by ChainVerifier</b>

Communication Channel Parameters:

Connection Security: FTP (FTP Using SSL/TLS) for Control Connection or FTP (FTP Using SSL/TLS) for Control Connection and Data Connection

Command Order: AUTH TLS, USER, PASS, PBSZ, PROT

Checkbox - Use X.509 Certificate.... checked (Certificate was provided by third party (customer issued) and uploaded to service_ssl certificate store on J2EE server)

Data Connection: Passive

Port: 10021

Keystore: service_ssl

X.509 Certificate & Private Key: ssl-credentials

Note: Initial handshaking occurs but connection is being dropped by the third party FTP Server when SSL certificate credentials are being validated. We also tried connecting to the third party FTPS server using standard FTPS client(FileZilla software), this connection gets established successfully with no certificate issues which means certificate and third party FTP Server is functioning correctly.

We therefore are thinking that the problem lies with our XI system being unable to load the certificate information correctly at the point when FTPS session is being established.

Your help and suggestions will be greatly appreciated.

Thanks and Best Regards
