Hi all,

I have generated certificate chain using Openssl(OpenSSL 0.9.8e). The certificate hierarchy is as follows:

ca.pem ---->cert1.pem---->cert2.pem----->last.pem

Openssl doesn't give any error when verifying these certificate chain(Certificate chain verification is successful) during TLS connection establishment(Connection establishment is successful) but when verified using Openssl command /openssl verify /gives following error:

*# openssl verify -CAfile ca.pem -untrusted cert1.pem cert2.pem last.pem*
cert2.pem: OK
last.pem: /C=IN/O=Xyz/OU=CableLabs Key Distribution Center/CN=kdc.xyz.com
error 20 at 0 depth lookup:unable to get local issuer certificate

The Subject and Issuer names in certificates are correct. Please let me know the cause of error and changes required in the certificate hierarchy.

Regards,
Vinay
