Question : Certificate chain verification fails with "verify error:num=19:self signed certificate in certificate chain"?

I purchased an SSL certificate from GoDaddy.com, and installed it on my domain at https://www.GiftsAtDesiHaat.com/. All looks and works fine except that the verification of the certificate chain says "verify error:num=19:self signed certificate in certificate chain". Would you happen to know why? This is causing failure of all my business transactions with Google Checkout. Here is what I am trying to verify the certificate chain:

$ openssl s_client -connect www.GiftsAtDesiHaat.com:443 -showcerts

CONNECTED(00000003)
depth=3 /L=ValiCert Validation Network/O=ValiCert, Inc./OU=ValiCert Class 2 Policy Validation Authority/CN=http://www.valicert.com//emailAddress=info@valicert.com
verify error:num=19:self signed certificate in certificate chain
verify return:0

Answer : Certificate chain verification fails with "verify error:num=19:self signed certificate in certificate chain"?

All root certificates are self signed by definition, the one you trust you collect into directory by default that is /etc/ssl/certs although firefox & kde have a separate one.

the command should have been:

openssl s_client -connect www.GiftsAtDesiHaat.com:443 -showcerts -CApath /etc/ssl/certs

to be able to validate the root certificate.
