Chapter 8      Establishing Cisco Secure ACS System Configuration
Global Authentication Setup
Note
Cisco Secure ACS requires that the certificate and CA files be in 
Base64-encoded X.509. You can also add the CA certificate by installing it 
outside of Cisco Secure ACS (in Windows). After you install it, you should be 
able to see the new CA in the CA list from within Cisco Secure ACS.
To add a new CA certificate to local certificate storage, follow these steps:
Step 1
In the navigation bar, click System Configuration.
Step 2
Click Certification Authority Setup.
Result: Cisco Secure ACS displays the CA Operations table.
Step 3
In the CA file name box, type the full directory path and name of the CA 
certificate file.
Step 4
Click Submit.
Result: Cisco Secure ACS displays the following message in the display area on 
the right:
New CA certificate is successfully added into the global system
certificate storage.
After you have installed a certificate in Cisco Secure ACS and added the required 
CAs, you can configure EAP-TLS in Global Authentication Setup and then restart 
Cisco Secure ACS.
Global Authentication Setup
Use this procedure to select and configure how Cisco Secure ACS handles 
extended options for authentication. In particular, you use this procedure to allow 
either EAP-MD5 or EAP-TLS, and to allow either MS-CHAP Version 1 or 
MS-CHAP Version 2, or both.
