Certificate Signing Request (CSR) Generation Instructions for Cisco ACS 3.2

General Information ID:    INFO168    Updated:    06/09/2017

Description


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.
     
    • Country Name (C): Use the two-letter code without punctuation for country, for example: US or CA.
    • State or Province (S): Spell out the state completely; do not abbreviate the state or province name, for example: California.
    • Locality or City (L): The Locality field is the city or town name, for example: Berkeley.
    • Organization (O): If your company or department has an &, @, or any other symbol using the shift key in its name, you must spell out the symbol or omit it to enroll.
    • Organizational Unit (OU): This field is the name of the department or organization unit making the request.
    • Common Name (CN): The Common Name is the Host + Domain Name. It looks like "www.symantec.com" or "symantec.com".
      NOTE: Symantec certificates can only be used on Web servers using the Common Name specified during enrollment. For example, a certificate for the domain "symantec.com" will receive a warning if accessing a site named "www.symantec.com" or "secure.symantec.com", because "www.symantec.com" and "secure.symantec.com" are different from "symantec.com".
       
  6. Cisco Secure ACS requires that one of the values be CN, such as CN=symantecprimary. You can specify multiple values. To do so, separate the values with commas. For example:  

    CN=www.symantec.com, O=Symantec Corporation, C=US, S=California, L=Mountain View
     
  7. 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.
  8. 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.
  9. In the Retype private key password box, retype the private key password.
  10. In the Key length list, choose 2048 bits.
  11. From the Digest to sign with list, select SHA1.
  12. 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.
  13. Verify your CSR
  14. 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).
  15. 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: INFO171
