CA trustpoints
Configure certificate on Cisco Adaptive Security Appliance using SCEP enrollment
Configure certificate on Cisco Adaptive Security Appliance using manual enrollment
Certificate configuration for external Access Edge interface
Create custom certificate for Access Edge using enterprise certificate authority

CA trustpoints

When generating a trustpoint, you must specify an enrollment method to be used with the trustpoint. You can use Simple Certificate Enrollment Process (SCEP) as the enrollment method (assuming you are using a Microsoft CA), where you use the enrollment url command to define the URL to be used for SCEP enrollment with the trustpoint you declared. The URL defined should be the URL of your CA.

You can also use manual enrollment as the enrollment method, where you use the enrollment terminal command to indicate that you will paste the certificate received from the CA into the terminal. Both enrollment method procedures are described in this section. Refer to the Cisco Security Appliance Command Line Configuration Guide for further details about the enrollment method.

In order to use SCEP, you need to download the Microsoft SCEP add-on from the following URL:

http://www.microsoft.com/Downloads/details.aspx?familyid=9F306763-D036-41D8-8860-1636411B2D01&displaylang=en

The SCEP add-on must be installed on the Microsoft CA that you are configuring the certificates on.

Download the SCEP add-on as follows:

Download and run scepsetup.exe.

Select local system account.

Deselect SCEP challenge phrase to enroll.

Enter the details of the CA.

When you click Finish, retrieve the SCEP URL. You will use this URL during trustpoint enrollment on Cisco Adaptive Security Appliance.

Security Certificate configuration on Lync Edge server for TLS federation

The following guide from Microsoft's TechNet Library (http://technet.microsoft.com/en-us/library/gg398409.aspx) explains how to configure certificates on Access Edge for TLS federation with Microsoft Lync. IM and Presence requires Mutual TLS authentication for federated connections, therefore you must configure Microsoft Lync certificates to support both Server and Client Authentication. When you follow the above guide, skip section 2 and move instead to section 3 which describes how to create a certificate request for the external interface of the Edge Server to support public IM connectivity with AOL. AOL has the same mutual TLS authentication requirement as IM and Presence. You can also use this guide to configure Lync Server to federate directly with IM and Presence over TLS.

For information about how to configure static routes on Lync server for direct federation, see Static route configuration for interdomain federation to Microsoft Lync within enterprise.

Security certificate exchange between Cisco Adaptive Security Appliance and AOL SIP access gateway

AOL requires that the Cisco Adaptive Security Appliance certificate is signed by a trusted Certificate Authority. AOL has an established trust list of Certificate Authorities (CA) such as those commonly used in Windows or those in libraries distributed with the major browsers. If you wish to use a CA that is not on the AOL trust list, work with your Cisco representative to provide this information to AOL.

A sample configuration workflow that describes in detail how to configure certificate exchange between Cisco Adaptive Security Appliance and a foreign domain (Microsoft Access Edge) using the Verisign CA is provided in the appendix of this guide. Use this procedure as a reference to configure certificate exchange between Cisco Adaptive Security Appliance and the AOL SIP Access Gateway using the Verisign CA. A high-level overview of the configuration steps is provided below.

To configure certificate exchange between Cisco Adaptive Security Appliance and the AOL SIP Access Gateway using the Verisign CA, complete these steps:

Download the AOL root certificate from https://pki-info.aol.com/AOL/.

Download the AOL member certificate from https://pki-info.aol.com/AOLMSPKI/index.html

Delete any old intermediate and signed certificate, and the trustpoint for the root certificate on Cisco Adaptive Security Appliance.

Create a new trust point on Cisco Adaptive Security Appliance for the AOL root certificate, see section Import IM and Presence certificate into Cisco Adaptive Security Appliance (steps 1-3).

Create a new trust point on Cisco Adaptive Security Appliance for the AOL member certificate.

Create a new trustpoint for the Verisign CA on Cisco Adaptive Security Appliance.

On Cisco Adaptive Security Appliance, import the root certificate, and then generate a Certificate Signing Request (CSR). See section Configure certificate on Cisco Adaptive Security Appliance using manual enrollment for a similar procedure.

Note
The IM and Presence server certificate subject CN must match FQDN of the IM and Presence server. The public Certificate on Cisco Adaptive Security Appliance for IM and Presence and the CN must be the same as the Federation Routing IM and Presence FQDN service parameter value.

Submit the CSR to the Verisign CA.

Verisign CA provides you with the following certificates:
Verisign signed certificate

Verisign subordinate intermediate root certificate

Verisign root CA certificate

On Cisco Adaptive Security Appliance, delete the temporary root certificate used to generate the Certificate Signing Request.

Import the Verisign subordinate intermediate root certificate to Cisco Adaptive Security Appliance.

Create a trustpoint for the Verisign root CA certificate on Cisco Adaptive Security Appliance.

Import the Verisign root CA certificate to Cisco Adaptive Security Appliance, and then import the Verisign signed certificate to Cisco Adaptive Security Appliance.

Provide the VeriSign root and intermediate certificates to AOL.

Note
You must provide AOL with the root CA if the CA is not already in the AOL trust list.
