1992392 - SSLException due to name mismatch in File Adapter

You have a File Sender/Receiver communication channel configured with an FTP transport protocol using SSL/TLS (FTPS).
The channel fails with the following error in the Communication Channel Monitoring:

Case1:

Error occurred while connecting to the FTP server "XXX": iaik.security.ssl.SSLCertificateException: Peer certificate rejected by ChainVerifier

If you colllect an XPI Inspector trace with Example 50 (XI Channel), according to SAP note #1514898 - "XPI Inspector for troubleshooting XI", you will see entries like the following:

ssl_debug(12): Received certificate handshake message with server certificate.
ssl_debug(12): Server sent a 2048 bit RSA certificate, chain has 2 elements.
ssl_debug(12): ChainVerifier: name mismatch: ABC != XYZ
ssl_debug(12): Sending alert: Alert Fatal: bad certificate
ssl_debug(12): Shutting down SSL layer...
ssl_debug(12): SSLException while handshaking: Peer certificate rejected by ChainVerifier

XYZ is the host name of FTP server. ABC is the Common Name (CN) field of the server certificate.

Case2:

In the following specific case, you will not see the above error, but only :

"Data connection TLS warning: SSL3 alert read: fatal: bad certificate"

Same solution will work for this only in case you have configured the Sender/Receiver File communication channel with passive mode. In the XPI Inspector trace you can see steps:

-Sending command 'PASV'
-with (227 Entering Passive Mode (IPaddress), 227)
-ftp server returns reply '227 Entering Passive Mode (IPaddress)'
