Configuring SPS for Sessions-initiated workflow

To configure SPS to use the joined SPP in Sessions-initiated (SPP-initiated) workflows, complete the following steps. For details on the workflow, see Using SPS with SPP.

Prerequisites
  • Minimum versions:

    • SPP version 2.8

    • SPS version 6.2 and newer, including 6.0.2 and newer versions of the 6.0.x branch, but excluding 6.1.x

  • You must have built an SPS cluster by promoting an SPS node to the role of the Central Management node, even if it is a single node. For more information, see Building a cluster.

Limitations
  • Only SSH and RDP sessions are supported.

  • Users must perform gateway authentication on SPS with the same username they have Entitlements for in SPP.

    • For SSH sessions, the gateway authentication can use a Local User Database, an LDAP server, or an Active Directory server as authentication backend.

      Note that SPP does not support every type of LDAP and Active Directory settings that SPS does. Verify that you can configure both appliances to access and retrieve data from the LDAP or Active Directory server.

    • For RDP sessions, SPS must be configured to act as a Remote Desktop Gateway. For details, see Using One Identity Safeguard for Privileged Sessions (SPS) as a Remote Desktop Gateway.

      The gateway authentication can use a Local User Database or an Active Directory server as authentication backend. When using an Active Directory server, note the following points.

      • Both SPS and SPP must use the same server, and be the member of the same domain as the Active Directory server.

      • SPP does not support every type of Active Directory settings that SPS does. Verify that you can configure both appliances to access and retrieve data from the Active Directory server.

      • SPS does not receive the domain of the authenticated user from the Domain Controller. SPS assumes that the user belongs to the same domain that SPS is joined into. (Configuring trust between the Domain Controller of SPS and the Domain Controller of the user does not solve this problem.)

  • You must use a uniform address for the target server. Use either its IPv4 address or its hostname everywhere: when configuring the Assets in SPP, the Connection Policies and Channel Policies in SPS, and also when the user sets the target address in the SSH/RDP application. Otherwise, the authentication will fail.

To configure SPS for Sessions-initiated workflow

    Configure Connection Policies on SPS to audit your sessions. Note that you have to complete these steps for each Connection Policy that uses SPP as a Credential Store. For the general steps on configuring Connection Policies, see Configuring connections.

  1. Select Credential Store > safeguard_default

  2. Select AA plugin > safeguard_default

  3. Select Usermapping policy > safeguard_default

  4. Configure gateway authentication. The users must perform gateway authentication on SPS with the same username they have Entitlements for in SPP. For details, see Configuring gateway authentication.

  5. When you are using an Approve/deny workflow on SPP, increase the Idle timeout setting of the Connection Policy. SPS will wait for an approval from SPP until half the time set in Idle timeout. For example, if the authorizer on SPP has 2 minutes to approve the access request, set the Idle timeout option on SPS to more than double this value, for example, 5 minutes.

Joining SPS to SPP

You can join your One Identity Safeguard for Privileged Sessions (SPS) deployment to your One Identity Safeguard for Privileged Passwords (SPP) deployment.

IMPORTANT: Joining your SPS and SPP appliances is an action that you cannot undo.

If the primary IP address of your SPS or SPP changes, you must repeat this procedure to rejoin the clusters.

Prerequisites
  • Your SPS deployment must be a SPS cluster (not a high-availability cluster, but a Central Management cluster). Even if your SPS deployment consists of a single, standalone node, you must convert it to the Central Management node of its own single-node cluster. For details, see Managing Safeguard for Privileged Sessions (SPS) clusters.

    Configuration synchronization must be enabled between the nodes of the SPS cluster. This is required so SPP entitlements work properly for each SPS node.

    NOTE:

    If you have multiple standalone SPS appliances, consider joining them to a cluster before joining SPP. In general, One Identity recommends creating a cluster if the nodes can use a common configuration, or later you might want to centrally search the data of every node. Creating a cluster from the SPS nodes after joining SPP is problematic and should be avoided.

  • You will need the primary IP address or the hostname of your SPP deployment that SPS can use to access SPP. Only IPv4 addresses are supported.

  • You will need the username and password to an SPP account that has "Appliance" and "Operations" permissions.

  • Verify that your SPS policies do not contain the safeguard_default string in their names. During the join process, SPS automatically creates and configures several policies and plugins. The name of these policies usually contains the string safeguard_default. Existing policies with such names will be overwritten.

  • The SPP and SPS nodes must be able to communicate on the tcp 8649 port. If needed, update your firewall policies.

  • During the join process, SPS must be able to access SPP using HTTPS on the tcp 443 port. This is required only once during the join process. If needed, update your firewall policies.

To join your SPS deployment to SPP

  1. (Optional) Create a configuration backup of SPS. For details, see Creating configuration backups.

  2. (Optional) Create a configuration backup of SPP. For details, see the Safeguard for Privileged Passwords Administration Guide, Backup and Retention settings.

  3. Login to the Central Management node of your SPS cluster. This node has Central Management listed in the Basic Settings > Cluster management > Roles field.

    Figure 330: Basic Settings > Cluster management — Joining SPS to SPP

  4. Navigate to Basic Settings > Cluster management > Join to SPP cluster and enter the primary IP address of SPP into the IPv4 address or hostname of SPP to join field. Only IPv4 addresses are supported.

  5. Click Join. Wait until you are redirected to SPP.

  6. Login to SPP. Wait until you are redirected to SPS.

  7. Wait until SPS creates and configures the policies and plugins required for the joint operation of SPS and SPP. This step can usually take up to a minute.

  8. You will receive a message:

    • If the join is unsuccessful, this message displays: Request failed. Check the credentials and the IP address you provided. For details on resolving errors, see SPP to SPS join issues and SPP to SPS join error resolution

    • If the join is successful, this message displays: SPS successfully joined to SPP. SPP automatically closes any open access requests.

  9. Log out from the SPS web interface.

Caution:

If the primary IP address of your SPS or SPP changes, you must repeat this procedure to rejoin the clusters.

SPP to SPS join error resolution

Common join error resolutions follow which may occur when joining SPS (SPP) to One Identity Safeguard for Privileged Sessions (SPS).

Typo in SPP's address, the address is not reachable
  • Error: The browser reports errors when SPS redirects to SPP's login page, for example, This site can’t be reached. The exact error message depends on the browser.

  • Resolution: Click the Back button of the browser and enter the correct address into the Pv4 address or hostname of SPP to join field.

Typo in SPP's address, the address is alive, but not an SPP
  • Error: After clicking the Join button, a web site other than SPP's Login interface is displayed.

  • Resolution: Click the Back button of the browser and enter the correct address into the Pv4 address or hostname of SPP to join field.

SPP's HTTPS certificate does not match its IP address or hostnam
  • Error message: Error joining to SPP: SPS has failed to join to SPP. For more information, see the error details. (JoinFailed)

  • Raw error:

    {
      "response": "Error sending request: SSLError: HTTPSConnectionPool(host='examplespp.company', port=443): Max retries exceeded with url: /service/core/v3/Cluster/SessionModules (Caused by SSLError(CertificateError(\"hostname 'examplespp.company' doesn't match '192.0.2.123'\",),))",
      "status": null,
      "url": "https://examplespp.company/service/core/v3/Cluster/SessionModules"
    }
  • Resolution:

    • If SPP's certificate contains SPP's IPv4 address in the Common Name or subjectAltName field, then enter that IP address when joining SPS to SPP.

    • If SPP's certificate contains only its DNS name in the Common Name or subjectAltName field, then use that hostname when joining SPS to SPP.

    • Otherwise, set up an SSL server certificate for SPP which matches its IP address in the certificate's Common Name or subjectAltNamefields (see SSL Certificates in the Safeguard Administration Guide) and retry joining. Wait about five minutes to let the timeout of the failed join request expire before starting a new join request after a failed incomplete one. (Alternatively, see Reversing the SPP to SPS join in the Safeguard Administration Guide.)

Typo in SPP credentials
  • Error: Login to the SPP web interface fails.

  • Raw error:

    {
            "error": "invalid_request",
            "error_description": "Access denied.",
            "success": false
        }
  • Resolution: Make sure that the correct username and password are entered in the SPP username: and SPP password: prompts.
SPP user has insufficient permission
  • Error message: Error joining to SPP: SPS has failed to join to SPP. For more information, see the error details. (JoinFailed)

     Authorization is required for this request.

           URL: https://192.0.2.123/service/core/v3/Cluster/SessionModules
           Status: 403
  • Resolution: When SPS redirects to SPP's Login interface, then login as an SPP user has "Appliance" and "Operations" permissions.
SPS is already joined to SPP
  • Error message: Error joining to SPP: SPS has failed to join to SPP. For more information, see the error details. (JoinFailed)

    The session connection has a missing, invalid, or non-unique
    value [ NodeId ].
    
           Code: 60657
           URL: https://192.0.2.123/service/core/v3/Cluster/SessionModules
           Status: 400
  • Resolution: See Reversing the SPP to SPS join in the Safeguard Administration Guide.
Joining takes too long (more than five minutes)
  • ERROR: Request to https://192.0.2.123/service/a2a/v2/PsmValidation failed, response (HTTP 403):

        {
            "Code": 60108,
            "Message": "Authorization is required for this request.",
            "InnerError": null
        }
  • Resolution: Make sure that SPS is not overloaded and try joining again.
