To install your Thawte SSL123 certificate on a Plesk 5.0 server, perform the following steps:
Step 1: Obtain the Thawte SSL123 Intermediate CA certificate
a) Download the Thawte Intermediate CA for Thawte SSL123 certificate: AR1384
Note: Be sure to use Vi or Notepad as word processing programs like Microsoft Wordpad may add additional characters that may render the certificate unusable.
b) Copy and paste the Intermediate CA into a text file and save as intermediate.txt
c) Download your certificate as per the instruction on the following solution: SO13187
Steps2. Installing your Thawte SSL123 certificate:
1. Copy and paste your certificate into Notepad.
2. From inside PSA, choose the domain in which you are installing the SSL certificate.
3. Access the domain's SSL section by clicking on the 'certificate' button. (If the 'certificate' button is grayed-out, this means the domain is set up for name-based hosting. If you want a domain to utilize all of the SSL capabilities available, that domain must be configured for IP-based hosting).
4. When a CSR (certificate signing request) is generated there are two different text sections, the RSA Private Key and the Certificate Request. When installing a certificate, the RSA Private Key text needs to be pasted into the block preceding the issued Thawte SSL123 certificate.
-----BEGIN RSA PRIVATE KEY-----
[[ECRYPTED BLOCK OF TEXT]]
-----END RSA PRIVATE KEY-----
[[ECRYPTED BLOCK OF TEXT]]
5. Paste the Private Key with the Certificate text into the 'Enter Certificate Text:' text box and press the 'Send Text' button. There should be a prompt that reads "Certificate Successfully Installed".
Step3. Install the Intermediate CA
1. From inside PSA, choose the domain in which you are installing the SSL certificate.
2. Access the domain's SSL section by clicking on the 'certificate' button.
3. Pay attention to the icon next to 'Use rootchain certificate for this domain '.
4. If the icon is [ON] then the rootchain certificate will be enabled for this domain. If the icon is [X] this function will be disabled.
5. Ensure the icon is [X] before continuing (you may need to click the ON/OFF button if the icon is set to [ON]):
6. Click the browse button and locate the intermediate.txt file you have saved earlier.
7. Then click the Send File button. This will upload the CA Bundle to the server.
8. Click the icon button again to set it to the [ON] state.
9. Test your certificate by using a browser to connect to your server. Use the https protocol directive (e.g. https://your server/) to indicate you wish to use secure HTTP, or use our installation checker on the following solution: SO9555
NOTE: The padlock icon on your browser will be displayed in the locked position if your certificates are installed correctly and the server is properly configured for SSL.
