Managed PKI for SSL - CSR Generation for Cisco ACS 3.2


This document provides instructions for generating a Certificate Signing Request (CSR) for Cisco ACS 3.2. If you are unable to use these instructions for your server, Symantec recommends that you contact Cisco.
Note: To generate a CSR, you will need to create a key pair for your server. These two items are a digital certificate key pair and cannot be separated. If you lose your public/private key file or your password and generate a new one, your SSL Certificate will no longer match.
Step 1: Generate a Key Pair and Certificate Signing Request

Note: All certificates that will expire after October 2013 must have a 2048 bit key size.

  1. In the navigation bar, click System Configuration.
  2. Click ACS Certificate Setup.
  3. Click Generate Certificate Signing Request.
  4. CiscoSecure ACS displays the Generate new request table on the Generate Certificate Signing Request page.
  5. In the Certificate subject box, type the values required by the CA you will submit the CSR to.
    • Common Name: The fully-qualified domain name to which your certificate will be issued.
    • Organization: The full legal name of your company.
    • Organizational Unit: Use this field to differentiate between divisions within an organization.
    • City or Locality: Usually the city of your organization's main office, or a main office for your organization.
    • State or Province: Enter the full name of your state or province. 
      Note: Make sure the State or Province is not abbreviated (e.g. California).
    • Country: Enter the two-character abbreviation of country in which organization resides (e.g. US).
  6. In the Private key file box, type the full directory path and name of the file in which the private key is saved, for example, c:\privateKeyFile.pem.
  7. In the Private key password box, type the private key password that you have would like to use. Symantec does not have access to this password and cannot recover it.
  8. In the Retype private key password box, retype the private key password.
  9. In the Key length list, choose 2048 bits.
  10. From the Digest to sign with list, select SHA2.
  11. Click Submit. CiscoSecure ACS displays a CSR in the display area, on the right, under a banner that reads:
    Now your certificate signing request is ready. You can copy and paste it into any certification authority enrollment tool. You have just created a key pair and a CSR.
  12. Verify your CSR
  13. To copy and paste the information into the enrollment form, open the file in a text editor that does not add extra characters (Notepad or Vi are recommended).
  14. Go to Enrollment. When enrolling for the SSL Certificate you will be asked to choose a server vendor, choose Apache. This will allow a certificate that is compatible with the Cisco ACS.
Contact Information
         During the verification process, Symantec may need to contact your organization. Be sure to provide an email address, 
         phone number, and fax number that will be checked and responded to quickly. These fields are not part of the certificate.
Once the SSL certificate has been issued, follow the steps from this link to install it on the server: INFO283
