Configure Easy VPN Remote for the Cisco VPN Client 4.x
Task 3 – choose an authentication method

Under the Authentication tab, enter the information for the authentication method that will be used. The VPN Client can connect as part of a group that is configured on the remote VPN device, or by supplying an identity digital certificate.

Group Authentication
The network administrator usually configures group authentication for the remote user. If this is not the case, use the following procedure:

Step 1 Click the Group Authentication radio button.
Step 2 In the Name field, enter the name of the IPSec group to which the remote user belongs. This entry is case-sensitive.
Step 3 In the Password field, enter the password, which is also case-sensitive, for the IPSec group to which the remote user belongs. The field displays only asterisks.
Step 4 Verify the password by entering it again in the Confirm Password field.

Mutual Group Authentication
To use mutual group authentication, a root certificate that is compatible with the central-site VPN installed on the system is needed. The network administrator can load a root certificate on the remote user’s system during installation of the VPN Client software. When mutual group authentication is used, the VPN Client software verifies whether the remote user has a root certificate installed. If not, it prompts the remote user to install one. Before the user can continue, a root certificate must be imported. When the root certificate has been installed, follow the steps for Group Authentication.

Certificate Authentication
For certificate authentication, perform the following procedure, which varies according the type of certificate that is being used:

Step 1 Click the Certificate Authentication radio button.
Step 2 Choose the name of the certificate that is being used from the menu.

If the field says No Certificates Installed and is shaded, then the VPN Client must enroll for a certificate before this feature can be used.
