Configuring connection between KUMA and Active Directory

You can connect only to one Active Directory domain. To do so, you must configure a connection to the domain controller.

To configure a connection to an Active Directory domain controller:

  1. In the application web interface, select Settings → Domain authorization.
  2. In the Authorization type drop-down list, select AD/ADFS.
  3. In the Active Directory group of settings, in the Base DN field, enter the DistinguishedName of the root record to search for access groups in the Active Directory catalog service.
  4. In the URL field, indicate the address of the domain controller in the format <hostname or IP address of server>:<port>.

    In case of server availability issues, you can specify multiple servers with domain controllers by separating them with commas. All of the specified servers must reside in the same domain.

  5. If you want to use TLS encryption for the connection with the domain controller, select one of the following options from the TLS mode drop-down list:
    • startTLS.

      When the startTLS method is used, first it establishes an unencrypted connection over port 389, then it sends an encryption request. If the STARTTLS command ends with an error, the connection is terminated.

      Make sure that port 389 is open. Otherwise, a connection with the domain controller will be impossible.

    • LDAPS.

      When using LDAPS, an encrypted connection is immediately established over port 636.

    • insecure.

    When using an encrypted connection, it is impossible to specify an IP address as a URL.

  6. If you enabled TLS encryption at the previous step, add a TLS certificate:
    • If you previously uploaded a certificate, select it from the Secret drop-down list.

      If no certificate was previously added, the drop-down list shows No data.

    • If you want to upload a new certificate, click the AD_plus button on the right of the Secret list. In the opened window, in the Name field, enter the name that will be displayed in the list of certificates after the certificate is added. Add the file containing the Active Directory certificate (X.509 certificate public keys in Base64 are supported) by clicking the Upload certificate file button. Click the Save button.

      The certificate will be uploaded and displayed in the Secret list.

  7. In the Timeout in seconds field, indicate the amount of time to wait for a response from the domain controller server.

    If multiple addresses are indicated in the URL field, KUMA waits for the specified number of seconds for a response from the first server. If no response is received during that time, the application contacts the next server. If none of the indicated servers responds during the specified amount of time, the connection will be terminated with an error.

  8. To configure domain authentication for a user with the KUMA general administrator role, specify the DistinguishedName of the Active Directory group the user belongs to in the General administrators group field. Additional roles for the General administrator are automatically activated in KUMA, therefore you do not need to add them separately.

    In the case when multiple groups are specified for a user in the same tenant, the role with the highest-level permissions is used, with additional roles, if additional roles are assigned.

    Filter input example: CN=KUMA team,OU=Groups,OU=Clients,DC=test,DC=domain.

  9. Click the Save button.

A connection with the Active Directory domain controller is now configured.

You can also check the connection for the previously entered domain controller connection settings.

To check the connection to the domain controller:

  1. In the application web interface, select Settings → Domain authorization.
  2. In the Authorization type drop-down list, select AD/ADFS.
  3. In the Test connection settings block, select the relevant secret in the User credentials field.

    If necessary, you can create a new secret by clicking the AddSecret button or change the settings of an existing secret by clicking the ChangeSecret button.

    The following formats for specifying a user are available in the User field: UserPrincipalName and domain\user.

  4. Click Test.

    After clicking the Test button, the system tests the connection with the domain and returns a notification with the test results. The system does not check if the users can log in or if the user group is configured correctly.

For domain authentication, add the groups for the KUMA user roles.

You can specify the groups only for the roles that require the configuration of domain authentication. You can leave the rest of the fields empty.

To add groups of user roles:

  1. In the application web interface, select Settings → Domain authorization.
  2. Under Administration groups, click Add role groups.
  3. In the Tenant drop-down list, select the tenant of the users for whom you want to configure domain authentication. The Shared tenant is displayed in the drop-down list, but you cannot assign a role to it because the only role in the Shared tenant is the Access to shared resources additional role, and additional roles do not participate in domain authentication.
  4. In the Selected roles drop-down list, specify the roles for the user. You can select multiple roles. The following values are available:
    • Tenant administrator
    • Tier 2 analyst
    • Tier 1 analyst
    • Junior analyst

    After you select the roles, a group filter field is displayed for each role. In the fields for each role, specify the DistinguishedName of the domain group. The users of this domain group must have the capability to perform authentication with their domain accounts. Group input example: CN=KUMA team,OU=Groups,OU=Clients,DC=test,DC=domain.

    You can define a separate set of role filters for each tenant.

    If no filter is specified for a role, this means that conditions for creating an account through domain authentication are not specified for that role. Authentication with that role is impossible.

    After the first authentication under a domain account, domain user cards are created for users in the Settings → Users section. For a domain user, the ability to change the main role (General administrator, Tenant administrator, Tier 2 analyst, Tier 1 analyst, Junior analyst) is blocked in the user card, while additional roles can be added or removed (Access to CII, Interaction with NCIRCC, Access to shared resources), including management of additional role assignment to tenants. Roles assigned in the Domain authorization section and roles assigned in the user card supplement each other. For the General administrator, additional roles in KUMA are automatically activated, therefore you do not need to add them separately. If the General administrator role was assigned to a domain user, and the General administrator role was subsequently revoked, additional roles must be reassigned in the user card in the Settings → Users section.

    You can specify only one domain group for each role. If you want to specify multiple groups, you must repeat steps 2 to 4 for each group while specifying the same tenant.

  5. If necessary, repeat steps 2–4 for each tenant for which you want to configure domain authentication with the following roles: Junior analyst, Tier 1 analyst, Tier 2 analyst, or Tenant administrator.
  6. Click the Save button.

The groups of user roles will be added. The defined settings will be applied the next time the user logs in to the KUMA web interface.

After the first authentication of the user, information about this user is displayed under Settings → Users. The Login and Password fields received from the domain cannot be edited. The user role will also be unavailable for editing. To edit a role, you will have to change the user role groups. Changes to a role are applied after the next authentication of the user. The user continues working under the current role until the current session expires.

If the user name or email address is changed in the domain account properties, these changes must be manually made in the KUMA account.
