Acceptto MFA for Palo Alto VPN
RADIUS is a protocol commonly used to authenticate, authorize and account for user access and actions. Acceptto offers a simple solution for adding multi-factor authentication (MFA) to Palo Alto VPN via its Radius solution. This manual illustrates how to configure both a Palo Alto device and an Acceptto appliance using RADIUS.
- An Acceptto Appliance connected to your user directory (for example Microsoft Active Directory).
- A user with administrative privileges for the Acceptto Appliance.
- The user population that is going to be authenticated via RADIUS must be enrolled in the It’sMe mobile application.
- A user with administrative privileges for the Palo Alto device.
Configure the Acceptto Appliance RADIUS interface
- Login to the Acceptto appliance admin panel with an administrative account and select RADIUS.
- Activate the RADIUS Service by selecting the toggle control (it is active by default).
- Activate the MS-CHAPv2 protocol by selecting the toggle control (it is active by default).
- LDAP/AD host - enter the IP address or fully qualified domain name of your Active Directory Server.
- LDAP bind user - enter a user that has privileges to create a machine account in your Active Directory.
- LDAP bind password - enter the password for the user.
- LDAP Base DN - enter The base DN path of Active Directory LDAP tree for searching users.
- NETBIOS domain - enter the NETBIOS domain name.
- Assigned computer name - enter the computer name that you want to be created in Active Directory. For example, radius1.
- REALM - enter the realm that is appended to your username. Usually, this is your domain name.
- Acceptto AD Group - enter the LDAP group that contains the users that can login via MFA (note that by default users outside of this group will have their access denied).
- Pre-login message - enter the message that your users are going to see on the It’sMe mobile application.
Configure the Palo Alto Global Protect Portal
- Configure a RADIUS Server:
- Open the Palo Alto administrative interface and navigate to Device tab > Server Profiles > RADIUS and click Add.
- In the Server profile dialog enter the configuration for your RADIUS.
- Profile Name: Enter a friendly name for this configuration.
- Timeout (sec): 120 seconds
- Retries: 1
- Authentication Protocol: PAP
- Name: A friendly name for the RADIUS Server.
- RADIUS Server: The IP address or Fully Qualified Domain Name (FQDN) of your RADIUS server.
- Secret: The string used to authenticate the Palo Alto Device to the RADIUS Server.
- Port: Leave this unchanged.
- Select Device, Authentication Profile, Add.
- Name: A friendly name for the Authentication Profile.
- Type: RADIUS
- Server Profile: The Server profile created in the previous step 1.b.
- User Domain: The domain used by your users (Optional)
- Allow List: Select all or the user group(s) that you want to use for this authentication profile.
- Failed Attempts: Configure this setting according to your security policy. (Optional)
- Lockout Time (min): Configure this setting according to your security policy. (Optional)
- In the Palo Alto administrative interface, select Network tab > Global Protect > Portals then click Add.
- Select the Authentication tab and change or add the authentication method to use the Authentication Profile created in step 2.
- Select OK and Commit.
Test your setup
- Open a console session to the Palo Alto device.
- Type test authentication authentication-profile "VPNAuth Profile Acceptto RADIUS" username demo password, where “VPN Auth Profile Acceptto RADIUS” is the profile created in step 2, the username demo is a valid user of your Active Directory, the command prompt will ask you to input the user’s password.
- The expected output should be similar to:
- After the line “Now send request to remote server” the mobile device associated with the user account should receive a push notification. Approval of the user notification should then cause the line “Authentication succeeded…” to appear.
- If the push notification is rejected then the message “Authentication failed…” will appear.
- You can also verify the configuration using the Global Protect VPN Client.
- Download and install the Global Protect Client. See this link for further information on how to obtain the GlobalProtect Client.
- Open the Global Protect Client and select the “cog” icon on the top right-hand corner, select Settings to open the GlobalProtect Settings menu.
- Select Add to configure the portal created in “Configure the Palo Alto Global Protect Portal” step 3.
- Open the GlobalProtect client and select Connect.
- A push notification is sent to your mobile device. Approval of the push notification will complete the VPN connection.
