Avaya 3.7 Manuel D’Utilisation

As an added benefit, all communications with the Directory Server can be secured by SSL 
(Secure Sockets Layer).

In order to enable SSL, a Public Key Infrastructure (PKI) is used for creating a signed certificate 
and an issuer’s certificate. Both signed certificates are then installed on the server. The issuer’s 
certificate is then installed in the policy server, the VPNmanager Console, and the devices 
belonging to the VPN domain. The PKI can be owned and operated by a third party called a 
Certification Authority, or it can be owned and run by your organization. After the certificates are 
installed, the policy server and the VPNmanager Console are started, and during login SSL 
services are started.

Explanation for 

1. An administrator uses Directory Server to send a Certificate Request to a PKI.

2. The PKI responds with a Signed Certificate.

3. The Issuer’s Certificate is sometimes called a Certificate Authority (CA) Certificate, and can 

be freely obtained from anyone running a PKI.

4. An Issuer’s Certificate is installed in the policy server and the VPNmanager Console.

5. The administrator uses VPNmanager to install an Issuer’s Certificate into the devices.

You can configure your VPNmanager to use SSL at anytime, however, it’s recommended that it 
be done before being put into service.
