SFSF adapter error: Peer certificate rejected by ChainVerifier

[ambrish_mishra]

We are trying to connect to Success factors system.The certificates have been imported image.png

Own certificate appears as a wild card which I am not too sure about however we copied the certificate with a specific name. The certificates have been stored in Trusted key store in sequence Own->Intm->Root.

We have chosen "Specify SSL server certificate" option in the SFSF communication channel and since the own certificate does not appear in the comm channel, I typed in the entry from the keystore name. The URL is correct. On ping, it gives an error "iaik.security.ssl.SSLCertificateException: Peer certificate rejected by ChainVerifier"

XPI inspector shows the logs:
