I'm trying to configure the Google checkout feature to a ZenCart e-commerce site running on suse10.2 configured with ISPConfig. I'm having a problem with the security certificate. I tried to follow the suggestions in the thread: http://www.howtoforge.net/forums/showthread.php?t=1854 but still no joy. the site is working fine on both IE and firefox but google is rejecting the certificate. Running: # openssl s_client -connect www.mysite.com:443 -showcerts < /dev/null shows: CONNECTED(00000003) depth=3 /L=ValiCert Validation Network/O=ValiCert, Inc./OU=ValiCert Class 2 Policy Validation Authority/CN=http://www.valicert.com//emailAddressfirstname.lastname@example.org verify error:num=19:self signed certificate in certificate chain verify return:0 --- Certificate chain 0 s:/O=www.mysite.com/OU=Domain Control Validated/CN=www.mysite.com i:/C=US/ST=Arizona/L=Scottsdale/O=GoDaddy.com, Inc./OU=http://certificates.godaddy.com/repository/CN=Go Daddy Secure Certification Authority/serialNumber=xxxxxxxx -----BEGIN CERTIFICATE----- etc. (changed the domain and xx'd out the serial number) I've added the httpd directive suggested by mjrpes (in the reference post, page 3) for the intermediate certificate and copied the .crt file to the /web2/ssl directory. I then restarted apache. I then added my site certificate using the control panel and again restarted apache. I trying to get a clean SSL chain so Google can properly call-back to my shopping cart. Any idea what I'm doing wrong in setting up the godaddy certificates? Your help is greatly appreciated.
