Web: Example for Configuring Agile Controller SSO for Internet Access Users (Users' HTTP Services Are Redirected to the Controller)

This section provides an example for configuring Agile Controller (Policy Center or Agile Controller) Single Sign On (SSO) for Internet access users when a FW works as an egress gateway. In redirected authentication, users access HTTP services, and the FW then redirects the HTTP requests to the Agile Controller portal authentication page. After the authentication succeeds, the users continue to access services.

Networking Requirements

An enterprise has deployed a FW as the egress gateway to connect the intranet to the Internet, as shown in Figure 1.

  • The Agile Controller identity authentication mechanism is enabled on the intranet, and information about users and user group is saved on a Agile Controller server.
  • Internet access users on the intranet include R&D employees and marketing employees.
Figure 1 Agile Controller SSO for Internet access users

The user management and authentication mechanisms of the FW must identify IP addresses on the intranet as users to implement user-specific behavior control and permission assignment. Requirements are as follows:

  • R&D employees and marketing employees can access HTTP services without proactively accessing the Agile Controller portal authentication page, because their HTTP requests will be automatically redirected to the Agile Controller portal authentication page.
  • After passing the authentication by entering correct Agile Controller accounts and passwords, R&D employees and marketing employees can access network resources. R&D employees and marketing employees are identified by the user names they use for Agile Controller authentication.
  • The FW saves department information, not user information. The permissions of authenticated users are controlled on the basis of the groups they belong to.

Configuration Roadmap

This example describes only how to configure user management and authentication.

The configuration roadmap is as follows:

  1. Add the FW on the Agile Controller server and configure the Agile Controller server on the FW to enable the FW and Agile Controller server to communicate.
  2. Configure a policy to import group information from the Agile Controller server to the FW.
  3. Set Agile Controller SSO parameters on the FW.
  4. Set a new user authentication option for the authentication domain. New users are temporary users after being authenticated.
  5. Set the URL of the redirected authentication page to the address of the Agile Controller portal authentication page for the users that directly access HTTP services.
  6. Configure an authentication policy to authenticate users before they access the Internet.
  7. Because the FW is deployed between users and the Agile Controller server, authentication packets pass through the FW. Therefore, to implement SSO, configure an authentication policy to disable the FW from authenticating the authentication requests destined for the Agile Controller server and configure security policies to ensure normal communication between the users, FW and Agile Controller server.

Description

Agile Controller server

  • Service Name: auth_server_tsm

  • Agile Controller IP Address: 10.2.0.50

  • Server Port: 8084

  • Encryption: AES128

  • Shared Key: Admin@123

On a FW, set the parameters for communication with a Agile Controller server.

The parameter settings on the FW must be consistent with those on the Agile Controller server.

User information import policy

  • Name: policy_import

  • Server Type: Agile Controller

  • Server Name: auth_server_tsm

  • Import Type: Import only user groups

  • Target User Group: /default

  • Automatic Synchronization from Server: 120 minutes

  • Overwrite local user records when the current user exists

Import groups from the Agile Controller server to the FW.

Parent group of new users

New users preferentially use the permissions of their parent groups on the server. If their parent groups do not exist on the server, users use the permission of the /default group.

All users passing Agile Controller authentication are new users for the FW.

Agile Controller authentication portal address

http://10.2.0.50:8080/portal

This address must be the same as the setting on the Agile Controller server.

Agile Controller SSO

  • Agile Controller SSO: Enable

  • Internet Access After Identity Authentication

Set SSO parameters on the FW and configure the FW to receive the user login and logout information from the Agile Controller server.

Procedure

  1. Add the FW on the Agile Controller server.

    The following example describes Agile Controller. The user interface may vary with the version. For details, refer to the Policy Center or Agile Controller product documentation of a specific version.

    1. Choose System Configuration > Server Configuration > Online Behavior Management Device.
    2. Click Add and set the following parameters.

      The Port must be the same as the Agile Controller SSO listening port on the FW in 6.

      The Key and Encryption Algorithm must be the same as the shared key and encryption algorithm in 4.

      If the FWs work in hot standby mode, you need to add Online Behavior Management Device twice on the Agile Controller server. The IP Address parameters must be set respectively to the real IP addresses of the active and standby device interfaces connecting to the Agile Controller server.

    3. Click OK.
  2. Choose Network > Interface, set IP addresses for interfaces and assign the interfaces to security zones.

    The following example describes how to configure interface GigabitEthernet 0/0/3. You can configure other interfaces based on the networking diagram.

    Zone

    trust

    IP Address

    10.3.0.1/24

  3. Choose Policy > Security Policy > Security Policy, click Add to configure security policies.
    1. Configure a security policy between the Trust zone (users) and DMZ (Agile Controller server) for users to get authenticated by the Agile Controller server.

      Name

      sec_policy_tsm

      Source Zone

      trust

      Destination Zone

      dmz

      Source Address

      10.3.0.0/24

      Destination Address

      10.2.0.0/24

      Action

      Permit

      If the URL of the authentication page is a domain name and a DNS server for resolving the URL is deployed in the DMZ, you need to enable the DNS service from the Trust zone to DMZ.

    2. Configure security policies between the DMZ (Agile Controller server) and Local zone for the Agile Controller server and FW to communicate.

      Name

      local_policy_tsm_01

      Source Zone

      local

      Destination Zone

      dmz

      Action

      Permit

      Name

      local_policy_tsm_02

      Source Zone

      dmz

      Destination Zone

      local

      Action

      Permit

    3. Configure a security policy to allow users to access the Internet.

      Name

      policy_sec_02

      Source Zone

      trust

      Destination Zone

      untrust

      Source Address

      10.3.0.0/24

      Action

      Permit

      Enable the DNS service for the Trust -> Untrust interzone to allow HTTP domain name resolution packets through.

  4. On a FW, choose Object > Authentication Server > TSM, click Add to set the parameters for communication with a Agile Controller server.

    The parameter settings on the FW must be consistent with those on the Agile Controller server. In most cases, the server port of Policy Center is 8080, and that of Agile Controller is 8084.

    Click Detect. In the dialog box that is displayed, click OK to check the connectivity to the Agile Controller server.

  5. On a FW, choose Object > User > User Import > Server Import, click Add to configure a policy to import user information from the Agile Controller server to the FW.

    User information on the Agile Controller server can be imported only to the default authentication domain.

  6. Choose Object > User > default, configure Agile Controller SSO and click Apply.

    Click Configure on the right of Server Import Policy. A dialog box is displayed. Click Import Immediately corresponding to policy_import. After the import is complete, the user groups and users on the Agile Controller server are displayed in User/User Group/Security Group Management List.

  7. Choose Object > User > Authentication Option > User-Defined Portal, Set Portal server URL to Agile Controller portal authentication page.

    The portal URL must be consistent with that of the Controller.

  8. Choose Object > User > Authentication Policy, click Add to configure authentication policies.
    1. Configure the action in the authentication policy for users to access the Agile Controller server as no-authentication so that the users' authentication packets can go through the FW to the Agile Controller server.

      Name

      auth_policy_tsm

      Source Zone

      Trust

      Destination Zone

      dmz

      Source Address/Region

      10.3.0.0/24

      Destination Address/Region

      10.2.0.50/32

      Action

      No authentication

    2. Configure the action in the authentication policy for users to access the other services as portal authentication so that the users' HTTP service access traffic triggers authentication.

      Name

      auth_policy_service

      Source Zone

      Trust

      Destination Zone

      untrust

      Source Address/Region

      10.3.0.0/24

      Action

      Portal authentication

      Template Name

      portal

  9. After the configuration is complete, you can configure security policies, PBR policies, bandwidth policies, quota control policies, proxy policies, and audit policies that reference the user and user group objects.

Verification

  • Access http://www.example.org/ as an R&D employee. The HTTP request is redirected to the authentication page. After entering the Agile Controller account and password, you can continue to access network resources.
  • Access http://www.example.org/ as a marketing employee. The HTTP request is redirected to the authentication page. After entering the Agile Controller account and password, you can continue to access network resources.
  • On the FW, choose Object > User > Online User to see information about online users.
