RSA-ACE is a commonly used two-factor authentication method for the authentication of network and VPN users. When authenticating with an RSA-ACE server, users can sign in with the username and password, consisting of PIN and RSA SecurID provided by a token.
Before you Begin
RSA-ACE does not provide group information. If you want to create groups, follow the instructions given in How to Configure Explicit Groups.
For authentication against the Barracuda NextGen Firewall F-Series using an RSA-ACE authentication server, verify that the Clear Node Secret is properly set:
Step 1. Configure the RSA-ACE Server
Before configuring RSA-ACE authentication, you must prepare the RSA-ACE server:
Create an Agent Host and add the users who want to authenticate over the Barracuda NextGen Firewall F-Series.
- Encryption = DES
- Type = Unix Agent
Assign Acting Server.
- Export the configuration to insert it in the RSA-ACE Authentication configuration as explained in Step 2.
Step 2. Configure RSA-ACE Authentication
- Go to CONFIGURATION > Configuration Tree > Box > Infrastructure Services > Authentication Service.
- In the left navigation pane, select RSA-ACE Authentication.
- Click Lock.
- Enable RSA-ACE as external directory service.
- In the RSA Configuration File section, import the configuration file that is provided by the RSA SecurID server (sdconf.rec).
- Enter the IP address of the RSA server.
- In the DNS Resolved IP field, enter the IP address that is used to connect to the RSA server. This IP address must match the configured client IP address that the server has; otherwise, the connection is refused.
- If group information is queried from a different authentication scheme, select the scheme from the User Info Helper Scheme list.
- Click Send Changes and Activate.
RSA-ACE SecurID Authentication Through the Remote Management Tunnel
To allow remote F-Series Firewalls to connect to the authentication server through the remote management tunnel, you must activate the outbound BOX-AUTH-MGMT-NAT Host Firewall rule. By default, this rule is disabled.
