    Hi All,

    I recently requested a thawte SSL cert for one of my customers. i have downloaded the crt and installed via the ISPConfig 3 CP. I have also included their 'bundle' crt.

    Things are basically working but I see in the Apache error log:

    Code:
    [Mon Feb 18 13:59:53 2013] [warn] RSA server certificate CommonName (CN) `www.sfpi.com' does NOT match server name!?
    
    If I dump the crt via openssl I see:

    Code:
    root@webserver2:/var/www/sfpi.com/ssl# openssl x509 -in www.sfpi.com.crt -noout -subject
    subject= /1.3.6.1.4.1.311.60.2.1.3=US/1.3.6.1.4.1.311.60.2.1.2=Ohio/businessCategory=Private Organization/O=Self Funded Plans, Inc./serialNumber=559576/C=US/ST=Ohio/L=Cleveland/CN=www.sfpi.com
    
    In the /etc/apache2/sites-available I see:

    Code:
        ServerName sfpi.com
        ServerAlias www.sfpi.com
    
    So, from the screen where I requested the SSL for this site I entered:

    Organizational Unit: www.sfpi.com
    SSL Domain: www.sfpi.com

    Should I have set the OU to 'sfpi.com' instead of 'www.sfpi.com'?
    But when I did that and requested from thawte, the cert came back w/o the 'www' :) So I'm confused :(

    Thanks,
    Danté

    You should ask Thawte if the certificate is valid for www.sfpi.com and sfpi.com. Usually that is the case (at least with the CAs I use to work with) - maybe Thawte has a different policy?
