Migrate to SAML from LDAP through the REST API

Secure, single sign-on (SSO) authentication to the Command and Discover appliances is easy to configure. However, if you have configured your ExtraHop appliance for remote authentication through LDAP, TACACS+, or RADIUS, changing to SAML permanently deletes all existing remote users and their customizations, such as saved dashboards, activity maps, reports (for Command appliances), and record queries (for Explore appliances).

This guide provides a series of example scripts that show you how to safely migrate user customizations from remote users to SAML through the REST API. For each script, you must replace the script variables with information about your environment.
Important:Customizations must be saved from the appliance where remote users have created them. For example, if a remote user has a critical dashboard on a Command appliance and a Discover appliance, you must complete these procedures on both appliances for that remote user.

If you prefer to engage a turn-key solution for migration, contact your ExtraHop sales representative.

Procedure overview

Migrating to a new remote authentication method is a complex process. Be sure you understand all of the steps before you begin and be sure to schedule a maintenance window to avoid disrupting users.

Before you begin

  1. Enable exception files on your Discover and Command appliances. If the ExtraHop system unexpectedly stops or restarts during the migration process, the exception file is written to disk. The exception file can help ExtraHop Support diagnose the issue that caused the failure.
  2. Create a backup of your Discover and Command appliances. Backup files include all users, customizations, and shared settings. Download and store the backup file off-appliance to a local machine.

Because changing the remote authentication method on the appliance effectively deletes all remote users, you must first create a (mirrored) local user for each remote user where you can temporarily transfer customizations and sharing settings. After transferring these settings once, you must configure SAML for the appliance, and then transfer the settings a second time from the local users to the SAML users. Finally, you can delete the temporary local users from the appliance.

Here is an explanation of each step:
  1. Retrieve metadata for customizations created by remote users.
  2. (Optional for Explore appliance users) Save record queries created by remote users to the setup user account.
  3. Retrieve remote users and user groups.
  4. Create a temporary local user account for each remote user that you want to preserve.
  5. Transfer customizations from remote user accounts to temporary local user accounts.
  6. Configure SAML on the appliance. (All remote users and user groups are deleted.)
  7. Create SAML user accounts for each remote user that was deleted. After the appliance is configured for SAML, you can create a remote account for your users before they log into the appliance for the first time.
  8. Recreate local user groups that were deleted.
  9. Transfer customizations and sharing settings from the temporary local user accounts to the new SAML user accounts. When your SAML users log in for the first time, their customizations will be available.
  10. Delete the temporary local user accounts.

Retrieve remote user customizations

The following Python script retrieves a list of remote user customizations and associated metadata and saves the information in JSON files. Run the script once for each type of customization after replacing the variables with information from your environment.

Environmental variables

The following variables enable the script to communicate with an appliance:
HOST
The IP address or hostname of the Discover or Command appliance.
APIKEY
The API key generated from the Discover or Command appliance.

Customization variables

The following variables specify a customization type. You must replace these variables each time that you run the script. For example, to retrieve dashboard metadata, specify OBJECT_TYPE=dashboards and OBJECT_FILE=dashboards.json:
OBJECT_TYPE
The type of customization metadata to retrieve. The following values are valid:
  • dashboards
  • activitymaps
  • reports
OUTPUT_FILE
The name of the JSON file to save customization metadata in. Keep these files on your machine to input into scripts later in the migration.
  • dashboards.json
  • activity_maps.json
  • reports.json
#!/usr/bin/python3

import json
import requests

HOST = 'extrahop.example.com'
API_KEY = '123456789abcdefghijklmnop'
OBJECT_TYPE = 'dashboards'
OUTPUT_FILE = 'dashboards.json'

headers = {'Authorization': 'ExtraHop apikey=%s' % API_KEY}

# Method that retrieves metadata for every object
def getObjects():
    url = HOST + '/api/v1/' + OBJECT_TYPE
    r = requests.get(url, headers=headers, verify=False)
    return r.json()

# Method that retrieves sharing settings for a specified object ID
def getSharing(object_id):
    url = HOST + '/api/v1/' + OBJECT_TYPE + '/' + str(object_id) + '/sharing'
    r = requests.get(url, headers=headers, verify=False)
    if r.status_code == 200:
        return r.json()
    else:
        print('Unable to retrieve sharing information for object ID ' + str(object_id))
        print(r.status_code)
        print(r.text)
        return None

eh_objects = getObjects()
if OBJECT_TYPE != 'reports':
    for eh_object in eh_objects:
        object_id = eh_object['id']
        eh_object['sharing'] = getSharing(object_id)

with open(OUTPUT_FILE, 'w') as outfile:
    json.dump(eh_objects, outfile)
Note:If the script returns an error message that the SSL certificate verification failed, make sure that a trusted certificate has been added to your appliance. Alternatively, you can add the verify=False option to bypass certificate verification. However, this method is not secure and is not recommended. The following code sends an HTTP GET request without certificate verification:
requests.get(url, headers=headers, verify=False)

(Explore appliance only) Save record queries

In the following steps, you will learn how to preserve record queries saved by a remote user.

Because saved queries can be accessed by all system users, you can export all saved queries to a bundle and then upload them after migrating to SAML. Imported record queries are assigned to the user that uploads the bundle. (For example, if you import queries from a bundle while logged in as the setup user, all of the queries list setup as the query owner.) After migration, remote users can view the saved record queries and save a copy for themselves.

This procedure must be completed from the Admin UI.

  1. Log into the ExtraHop appliance with the setup user account.
  2. Click the System Settings icon and then select Bundles.
  3. From the Bundles page, select New.
  4. Type a name to identify the bundle.
  5. Click the arrow next to Queries in the Contents table and select the checkboxes next to the saved queries you want to export.
  6. Click OK. The bundle appears in the table on the Bundles page.
  7. Select the bundle and click Download. The queries are saved to a JSON file.

Next steps

After migration, upload the bundle to restore the saved record queries.

Retrieve remote users

The following Python script retrieves a list of remote users and their associated metadata and then saves the information in a JSON file named user_map.json. Replace the variables with information from your environment before you run the script.

Environment variables

The following variables enable the script to communicate with an appliance:
HOST
The IP address or hostname of the Discover or Command appliance.
APIKEY
The API key generated from the Discover or Command appliance.
Important:If an appliance includes duplicate LDAP user account names, the script will fail and list the duplicate names in the output. LDAP user account names are case sensitive, but SAML user account names are not. You must rename duplicate LDAP user account names before migrating them. For example, if you have LDAP user names user_1 and User_1, you must rename one of those accounts before migrating to SAML.

Create temporary local user accounts

The following Python script creates a temporary local user account for each remote user account on an appliance.

The script must be located in the same directory as the user_map.json file that contains the list of remote users. Replace the variables with information from your environment before you run the script.

Environment variables

The following variables enable the script to communicate with an appliance:

Configure SAML on the appliance

Depending on your environment, configure SAML. Guides are available for both Okta and Google. After you configure SAML on your ExtraHop appliance, you are able to create accounts on the appliance for your remote users, and transfer their customizations before they log in for the first time.

Create SAML user accounts

The following Python script creates SAML user accounts for each deleted remote user account on an appliance.

The script must be located in the same directory as the user_map.json file that contains the list of remote users. Replace the variables with information from your environment before you run the script.
Note:Verify the required format for usernames that are entered in the Login ID field with the administrator of your Identity Provider. If the usernames do not match, the remote user will not be matched to the user created on the appliance.

Environment variables

The following variables enable the script to communicate with an appliance:

HOST
The IP address or hostname of the Discover or Command appliance.
APIKEY
The API key generated from the Discover or Command appliance.
Note:The script generates SAML usernames through the generateName() method. By default, the script creates new usernames by appending @example.com to the end of the remote username. You must configure the method to generate usernames according to your SAML user account naming standard. Verify how to format usernames with the administrator of your Identity Provider.

You can also specify SAML usernames in a CSV file. To configure the script to retrieve usernames from a CSV file, set the READ_CSV_FILE variable in the script to True. The CSV file must meet the following requirements:

  • The CSV file must not contain a header row.
  • Each row of the CSV file must contain the following two columns in the specified order:
    ExtraHop username SAML username
  • The CSV file must be named remote_to_saml.csv and be located in the same directory as the Python script.

Transfer customizations to SAML user accounts

The following Python script transfers customizations from the temporary local user accounts to the SAML user accounts created on the appliance. Run the script once for each type of customization after replacing the variables with information from your environment. For example, if you want to preserve dashboards and activity maps, you will run the script once with the customization variables for dashboards and once with the customization variables for activity maps.

Environment variables

The following variables enable the script to communicate with an appliance:
HOST
The IP address or hostname of the Discover or Command appliance.
APIKEY
The API key generated from the Discover or Command appliance.

Customization variables

The following variables specify a customization type. You must replace these variables each time that you run the script. For example, to transfer dashboards ownership, specify OBJECT_TYPE=dashboards and OBJECT_FILE=dashboards.json:
OBJECT_TYPE
The type of customization to transfer. The following values are valid:
  • dashboards
  • activitymaps
  • reports
OBJECT_FILE
The name of the JSON file that includes the customization metadata. These files must be located in the same directory as the Python script along with the user_map.json file that contains the list of remote users. The following values are valid:
  • dashboards.json
  • activity_maps.json
  • reports.json
#!/usr/bin/python3

Delete temporary local user accounts

The following Python script deletes temporary local user accounts.

The script must be located in the same directory as the user_map.json file that contains the list of remote users. Replace the variables with information from your environment before you run the script.

Environment variables

The following variables enable the script to communicate with an appliance:
HOST
The IP address or hostname of the Discover or Command appliance.
APIKEY
The API key generated from the Discover or Command appliance.
Warning:This script permanently deletes user accounts. When a user is deleted, all customizations that are owned by that user are also deleted. Make sure that you have transferred customizations from local user accounts before running this script.
