On the Barracuda CloudGen Firewall, you can introduce additional authentication schemes, for example, to configure a second proxy server in your network with an alternative authentication server. There is no limit to the number of authentication schemes that you can add.
Configure an Additional Authentication Scheme
- Go to CONFIGURATION > Configuration Tree > Box > Infrastructure Services > Authentication Service.
- Click Lock.
- In the left menu, click Additional Schemes.
- In the Schemes section, click + to add an entry for the additional authentication scheme.
- Enter a Name for the additional authentication scheme.
- Enable the scheme to start the authentication processes.
- Select the scheme from the Method list.
- Configure the settings applicable to the selected scheme:
- MSNT Settings – For information on the settings in this section, see How to Configure MSNT Authentication.
- MSAD Settings – For information on the settings in this section, see How to Configure MSAD Authentication.
- RADIUS Settings – For information on the settings in this section, see How to Configure RADIUS Authentication.
- LDAP Settings – For information on the settings in this section, see How to Configure LDAP Authentication.
- RSA-ACE Settings – For information on the settings in this section, see How to Configure RSA-ACE SecurID Authentication.
- CloudGen Firewall Local Authentication Settings – For information on the settings in this section, see: How to Configure NGF Local Authentication.
- TACACS+ Settings – For information on the settings in this section, see How to Configure TACACS+ Authentication.
- OSCP Settings – For information on the settings in this section, see How to Configure OCSP Validation.
- In the Filter Settings section, select the scheme from the User Info Helper Scheme list if group information is queried from a different authentication scheme. For example, select LDAP if RADIUS is used for identity verification but group information must be queried from an LDAP directory.
In the Group Filter Patterns table, you can add patterns to filter group information from the directory service.
Example:- Group Filter Pattern:
*SSL*
- User01:
CN=foo, OU=bar, DC=foo-bar, DC=foo
- User02:
CN=SSL VPN, DC=foo-bar, DC=foo
In this example, User01 does not have the
*SSL*
pattern in its group membership string and will not match in group-based limitations.- Group Filter Pattern:
- Click OK.
- Click Send Changes and Activate.
