Configure TACACS+ Authentication for Panorama Administrators

You can use a TACACS+ server to authenticate administrative access to the Panorama web interface. You can also define Vendor-Specific Attributes (VSAs) on the TACACS+ server to manage administrator authorization. Using VSAs enables you to quickly change the roles, access domains, and user groups of administrators through your directory service, which is often easier than reconfiguring settings on Panorama.
  1. Add a TACACS+ server profile.
    The profile defines how Panorama connects to the TACACS+ server.
    1. Select
      Panorama
      Server Profiles
      TACACS+
      and
      Add
      a profile.
    2. Enter a
      Profile Name
      to identify the server profile.
    3. Enter a
      Timeout
      interval in seconds after which an authentication request times out (default is 3; range is 1–20).
    4. Select the
      Authentication Protocol
      (default is
      CHAP
      ) that Panorama uses to authenticate to the TACACS+ server.
      Select
      CHAP
      if the TACACS+ server supports that protocol; it is more secure than
      PAP
      .
    5. Add
      each TACACS+ server and enter the following:
      • Name
        to identify the server
      • TACACS+ Server
        IP address or FQDN
      • Secret
        /
        Confirm Secret
        (a key to encrypt usernames and passwords)
      • Server
        Port
        for authentication requests (default is 49)
    6. Click
      OK
      to save the server profile.
  2. Assign the TACACS+ server profile to an authentication profile.
    The authentication profile defines authentication settings that are common to a set of administrators.
    1. Select
      Panorama
      Authentication Profile
      and
      Add
      a profile.
    2. Enter a
      Name
      to identify the profile.
    3. Set the
      Type
      to
      TACACS+
      .
    4. Select the
      Server Profile
      you configured.
    5. Select
      Retrieve user group from TACACS+
      to collect user group information from VSAs defined on the TACACS+ server.
      Panorama matches the group information against the groups you specify in the Allow List of the authentication profile.
    6. Select
      Advanced
      and, in the Allow List,
      Add
      the administrators that are allowed to authenticate with this authentication profile.
    7. Click
      OK
      to save the authentication profile.
  3. Configure Panorama to use the authentication profile for all administrators.
    1. Select
      Panorama
      Setup
      Management
      and edit the Authentication Settings.
    2. Select the
      Authentication Profile
      you configured and click
      OK
      .
  4. Configure the roles and access domains that define authorization settings for administrators.
    1. Configure an Admin Role Profile if the administrator will use a custom role instead of a predefined (dynamic) role.
    2. Configure an Access Domain if the administrator uses a Device Group and Template role.
  5. Commit your changes.
    Select
    Commit
    Commit to Panorama
    and
    Commit
    your changes.
  6. Configure the TACACS+ server to authenticate and authorize administrators.
    Refer to your TACACS+ server documentation for the specific instructions to perform these steps:
    1. Add the Panorama IP address or hostname as the TACACS+ client.
    2. Add the administrator accounts.
      If you selected
      CHAP
      as the
      Authentication Protocol
      , you must define accounts with reversibly encrypted passwords. Otherwise, CHAP authentication will fail.
    3. Define TACACS+ VSAs for the role, access domain, and user group of each administrator.
  7. Verify that the TACACS+ server performs authentication and authorization for administrators.
    1. Log in the Panorama web interface using an administrator account that you added to the TACACS+ server.
    2. Verify that you can access only the web interface pages that are allowed for the role you associated with the administrator.
    3. In the
      Monitor
      ,
      Policies
      , and
      Objects
      tabs, verify that you can access only the virtual systems that are allowed for the access domain you associated with the administrator.
