Geotrust will email you your certificate. If the certificate is an attachment (Cert.cer), you can use the file. If the certificate is in the body of the email, copy and paste it into a text file (such as OriginalCert.txt) using Vi or Notepad. Do not use Microsoft Word or other word processing programs that may add characters. Confirm that there are no extra lines or spaces in the file.
1. Save the certificate file from Geotrust along with the Intermediate file into a directory on the server. For example: /usr/local/ssl
2. Creating a chained certificate is a matter of performing a few command line operations to 'cat' or combine your public certificate and the Geotrust Intermediate certificate together. These operations cannot currently be performed from the web Admin Interface. In an example, if your public certificate is in the file 'my.pub' and the Geotrust Intermediate certificate is in the file 'ca.pub', type the following command: cat my.pub ca.pub > chained.pub
3. Open the Zeus Web Controller. For example: http://server:9090
4. From the left-hand menu click SSL Certificates
5. Open the chained.pub file that was created earlier and copy all of the text. Paste this into the certificate text box.
6. Click Ok
