This article describes how to implement Clientless single sign on authentication with Active Directory integration.

Cyberoam ADS integration feature allows Cyberoam to map the users and groups from Active Directory for the purpose of authentication.

Prerequisites:

NetBIOS Domain name

FQDN Domain name

Search DN

Active Directory Server IP address

Administrator Username and Password (Active Directory Domain)

IP address of Cyberoam Interface connected to Active Directory server

Import AD groups

Configure Clientless SSO

Configuring ADS authentication

Logon to Cyberoam Web Admin Console and follow the below given steps:

Step 1: Create ADS User Groups

Instead of creating AD groups again in Cyberoam, you can import AD groups into

Cyberoam using Import Wizard.

One can import groups only after integrating and defining AD parameters into

Cyberoam.

Step 2: Configure Cyberoam to use Active Directory

Go to Identity Authentication Authentication Server and click Add to configure Active Directory parameters

Cyberoam allows implementing AD integration in two ways:

Tight Integration With tight integration, Cyberoam synchronizes groups with AD every time the user tries to logon. Hence, even if the group of a user is

changed in Cyberoam, on subsequent log in attempt, user logs on as the

member of the same group as configured in Active Directory. In this case group

membership of each user is as defined in the Active Directory.

Loose Integration With loose integration, Cyberoam does the Group management and does not synchronize groups with AD when user tries to logon.

By default, users will be the member of Cyberoam default group irrespective of

Active Directory group, administrator can change the group membership.

Cyberoam will use authentication attribute for authenticating users with Active

Directory.

Parameters Values

Server Type Active Directory

Server Name AD_Server

Server IP 192.168.1.1

Port 389 It is the port on which ADS server listens for the authentication requests. If your AD server is using another port, specify port number in Port field.

NetBios Domain elitecore If you do not know NetBIOS name, refer to section Determine NetBIOS Name, FQDN and Search DN.

ADS Username administrator Active Directory Administrator Username

Password As per your requirement Active Directory Administrator password

Integration Type Loose Integration with Cyberoam

Domain Name elitecore.com

Search Queries DC=elitecore, DC=com

Click Test Connection to check whether Cyberoam is able to connect to the Active Directory or not. If Cyberoam is able to connect to the Active Directory, click OK to

save the configuration.

Step 3: Select Active Directory as Authentication Server

Go to Identity Authentication Firewall and select Active Directory as preferred authentication server.

Authentication Server List displays all the configured servers while Selected

Authentication server List displays servers that will be used for authentication when

user tries to login.

In case of multiple servers, authentication request will be forwarded as per the order

configured in the Selected Authentication server List

Note:

By default, local database is selected. Make sure that the Active Directory server is

selected and it is configured on top in the Selected Authentication server List.

You can select 2 authentication mechanisms: The one on top will be primary and the

other one will be the secondary. In case primary server is not responding, Cyberoam

will attempt to check in the secondary server.

Step 4: Test Active Directory integration

Go to http://:8090 to open the Captive Portal (HTTP client)

login page.

Specify username and password

Username will be displayed on Identity Live Users page if user is able to log on to Cyberoam successfully.

This completes the AD configuration.

Import AD Groups

To import AD groups into Cyberoam use Import Wizard before configuring for single

sign on.

Clientless Single Sign on Implementation

Transparent Authentication (Clientless Single Sign on)

Cyberoam introduces Clientless Single Sign On as a Cyberoam Transparent Authentication Suite (CTAS).

With Single Sign On authentication, user automatically logs on to the Cyberoam when logs on to Windows through his windows username and password. Hence, eliminating the need of multiple logins and username & passwords.

But, Clientless Single Sign On not only eliminates the need to remember multiple passwords Windows and Cyberoam, it also eliminates the installation of SSO clients on each workstation. Hence, delivering high ease-of-use to end-users, higher levels of security in addition to lowering operational costs involved in client installation.

Cyberoam Transparent Authentication Suite (CTAS)

CTA Suite consists of

CTA Agent It monitors user authentication request coming on the domain controller and sends information to the Collector for Cyberoam authentication.

CTA Collector It collects the user authentication request from multiple agents, processes the request and sends to Cyberoam for authentication.

How does Cyberoam CTA Agent work?

User Authentication Information Collection Process

1. User tries to log on to the Active Directory Domain Controller from any workstation in LAN. Domain Controller tries to authenticate user credentials.

2. This authentication process is captured and communicated to CTA Collector over default port 5566 by CTA Agent real time.

3. CTA Collector registers user in the Local database and communicates user information to Cyberoam over the default port 6060

4. Cyberoam queries Active Directory to determine users group membership and registers user in Cyberoam database

Based on data from CTA Agent, Cyberoam queries AD server to determine group membership and based on which access is granted or denied. Users logged into a workstation directly i.e. locally but not logged into the domain will not be authenticated and are considered as Unauthenticated or Guest user. For users that are not logged into the domain, the HTTP Login screen prompting for a manual login will be displayed for further authentication.

Step 5: Installing CTA Suite

Download CTA Suite from www.cyberoam.com/cyberoamclients.html

Extract ctas.rar and install CTA Suite on Domain controller by following the on-screen instructions. Administrative right is required to install CTA Suite.

Check for Cyberoam Transparent Authentication Suite tab from Start All Programs.

If installed successfully, Cyberoam Transparent Authentication Suite tab will be added.

Consider the below given hypothetical network example where single domain controller is configured and follow the below given steps to configure Cyberoam Transparent Authentication:

Step 6: Configure CTA Collector from CTA Collector Tab on Primary Domain Controller

If logoff detection settings is enabled and firewall is configured on the Workstation, please allow the traffic to and from Domain controller.

For E.g. If ping is selected in log off detection and workstation firewall does not allow ping, Cyberoam will always detect user as logged out.

Step 7: Configure Agent from CTA Agent Tab on Primary Domain Controller

Step 8: Configure Collector Port in Cyberoam

Logon to CLI Console with default password, go to Option 4 Cyberoam Console and execute following command at the prompt:

console>cyberoam auth cta enable

console>cyberoam auth cta collector add collector-ip collector-port

Step 9. Configure CTAS Fault Tolerance

For Cyberoam versions 10.02.0 Build 473 onwards, you can configure high availability of collectors by executing the following commands:

console> cyberoam auth cta collector add collector-ip collector-port

create-new-collector-group

console> cyberoam auth cta collector add collector-ip collector-port

collector-group

Step 9: Enable Security Event logging on Active Directory

This completes the configuration.

Determine NetBIOS Name, FQDN and Search DN

On the ADS server:

Go to Start Programs Administrative Tools Active Directory Users and Computers

Right Click the required domain and go to Properties tab

Search DN will be based on the FQDN. In the given example FQDN is elitecore.com and Search DN will be DC=elitecore, DC=com
