12.4 Diagnostic Procedures, Vault/CPM/PSM Error Codes & System Recovery

12.4 Diagnostic Procedures, Vault/CPM/PSM Error Codes & System Recovery

Quick Answer: Troubleshooting CyberArk PAM requires correlating timestamps across three primary log streams: italog.log on the Digital Vault (security events, authentication, and firewall blocks), pm.log / PMTrace.log on the CPM (plug-in execution and target communication errors), and PSMConsole.log / PSMTrace.log on the PSM (session brokering and AppLocker blocks). Critical error codes include CACPM243E (password mismatch, resolved via reconciliation), CACPM305E (target access denied or connection timeout), PSMIN136E / PSMSR126E (dispatcher blocked by AppLocker), and ITATS006E (station firewall unauthorized). For emergency recovery when all administrative access is lost, administrators log into the local Vault console as the built-in Master user with the physical Master CD (recprv.key) mounted.

Troubleshooting Methodology & Cross-Tier Log Correlation

CyberArk troubleshooting follows a structured three-tier diagnostic methodology:

1. Identify the Failure Domain: Determine whether the failure occurred during Authentication (PVWA/IdP/LDAP), Credential Lifecycle (CPM to target), Session Brokering (PSM jump host to target), or Data Storage/Policy (Digital Vault).
2. Verify Network Connectivity & Ports: Validate TCP/UDP socket paths using PowerShell (Test-NetConnection -Port 1858), ensuring firewalls have not dropped legitimate traffic.
3. Cross-Tier Timestamp Correlation: Extract timestamps and error codes, then search corresponding log files chronologically across involved components.

High-Yield Error Codes & Targeted Remediation

1. Central Policy Manager (CPM) Lifecycle Errors

CACPM305E / CACPM306E: Failed to Change Password on Target

• Message Syntax: CACPM305E Error in changepassword to user <username> on domain <target_address>. Reason: <detailed_reason>
• Underlying Cause: CPM reached the target, but the target operating system or directory rejected the password change request. Causes include:
  • Access Denied: Managed account lacks rights to update its own password.
  • Connection Timeout: Firewalls blocked management ports (TCP 445/135 for Windows; TCP 22 for Unix; TCP 1433/1521 for databases).
  • Password Policy Violation: Generated password violated target complexity, length, or age rules.
• Remediation: Inspect target security logs (Event 4723/4724). Adjust platform password rules in PVWA (e.g., MinPasswordAge, PasswordLength). Verify network routing between CPM and target.

CACPM243E: Failed to Verify Password

• Message Syntax: CACPM243E Failed to verify password on target machine <target_address>. Reason: Logon failure: unknown user name or bad password.
• Underlying Cause: Credential desynchronization. The password stored in the Vault does not match the active password on the target endpoint.
• Remediation: Do NOT attempt repeated password changes, which will fail and risk lockout. Execute a Password Reconciliation task:
  • CPM leverages an assigned Reconcile Account associated with the target platform.
  • The Reconcile Account authenticates with elevated rights and forcefully resets the target password to a newly generated secret.
  • CPM updates the Vault object, restoring synchronization without knowing the old invalid password.

2. Privileged Session Manager (PSM) Connection Errors

PSMIN136E / PSMSR126E: Connection Component Execution Blocked

• Message Syntax: PSMIN136E Failed to execute process [AutoIt3.exe]. Reason: Access is denied.
• Underlying Cause: Microsoft Windows AppLocker enforces application whitelisting on hardened PSMs. Deploying a new connection component, upgrading Chrome, or adding a client without updating AppLocker rules causes the kernel driver to block execution.
• Remediation:
  1. Inspect Windows Event Viewer under Applications and Services Logs \ Microsoft \ Windows \ AppLocker \ EXE and DLL (confirm Event ID 8004).
  2. Add an authorizing entry into PSM\Hardening\PSMConfigureAppLocker.xml.
  3. Execute the hardening script: .\PSMConfigureAppLocker.ps1.
  4. Restart the CyberArk Privileged Session Manager service.

3. Digital Vault Security & Access Errors

ITATS006E: Station Is Not Permitted to Logon

• Message Syntax: ITATS006E Station <IP_Address> is not permitted to logon to this Vault.
• Underlying Cause: Request originated from an IP blocked by the Vault Windows Firewall or forbidden by workstation restrictions on the Vault user identity.
• Remediation: For new components, add the IP to DBParm.ini under AllowNonStandardFWAddresses=Yes or modify the Vault user's permitted workstations list in the PrivateArk Client.

ITATS103E: Authentication Failure for User

• Message Syntax: ITATS103E Authentication failure for user <username>.
• Underlying Cause: Incorrect credentials supplied, maximum invalid logon threshold exceeded (MaxInvalidLogons), or account suspended.
• Remediation: Unlock the account via PrivateArk Client or execute: CAVaultManager.exe UnlockUser /User <username>.

Break-Glass Emergency Vault Recovery: The Master User

In catastrophic scenarios—such as domain failure, loss of administrative passwords, or total administrator lockout—normal access through PVWA becomes impossible. CyberArk provides a break-glass recovery mechanism centered on the Master user.

Master User Security Controls & Access Workflow

• Unique Identity & Restrictions: The Master account possesses root cryptographic authority across all Safes and configurations. It is strictly prohibited from authenticating via PVWA or network sockets; it requires local physical console logon using the PrivateArk Client.
• Cryptographic Requirement: Authenticating requires the Master installation password and the Master Emergency Recovery Key (recprv.key).

Emergency Access Procedure

1. Retrieve the physical Master CD or USB drive housing recprv.key from secure dual-custody storage.
2. Mount the recovery media on the Vault server (e.g., E:\recprv.key).
3. In Server\Conf\DBParm.ini, configure the pointer: RecoveryPrvKey=E:\recprv.key.
4. Launch PrivateArk Client on the Vault desktop and connect to 127.0.0.1.
5. Authenticate as Master using the Master password.
6. Reset the Administrator account password, unlock suspended users, or repair corrupted Safe permissions.
7. Immediately log off, remove RecoveryPrvKey from DBParm.ini, return the Master CD to dual-custody storage, and restart the PrivateArk Server service to purge keys from memory.

Assembling Logs for a Support Case: CollectLogs and xRay

Correlating logs manually is the right approach while you are diagnosing. Once you escalate to CyberArk Support, the expectation reverses: submit a complete, tool-generated log bundle rather than hand-picked files, because the first support action on an incomplete bundle is to ask for the rest.

Two collectors cover the estate:

xRay is CyberArk's free log-collection agent. It is run locally on the component server, gathers that component's logs and the relevant configuration and environment data, and packages them into a single archive for attachment to the case. Two behaviours are worth knowing before you run it under pressure:

• On the PSM, Digital Vault, and Disaster Recovery Vault, xRay collects all logs by default and the selection cannot be narrowed — do not plan on trimming the bundle on those hosts.
• xRay is versioned independently of PAM, and old versions are retired. Support declines bundles from unsupported tool versions, so confirm you are running a current release before collecting.

A Practical Escalation Sequence

1. Fix the clock question first. Note the exact timestamp and time zone of the failure on each host; a bundle whose hosts disagree on time is far harder to correlate.
2. Reproduce the failure if it is reproducible, so the logs contain a clean, bounded occurrence rather than weeks of noise.
3. Run the collector on every component in the path, not only the one that displayed the error. A PSM connection failure routinely requires PSM, PVWA, and Vault bundles, because the fault may be a Safe permission, an AppLocker rule, or a Network Area restriction.
4. Record the versions of each component and of xRay itself.
5. State the exact error code — CACPM243E, PSMIN136E, ITATS006E — in the case description. The codes in the tables above route the case far faster than a prose description of the symptom.
