CA Integration Issues

This section helps to diagnose and resolve problems related to Certificate Authority (CA) connectors configured in CERTInext. These issues typically affect certificate issuance, renewal, revocation, or status synchronization between CERTInext and the connected CA (Public or Private).

CA integration failures can interrupt automated provisioning workflows and delay certificate lifecycle operations.

Common Symptoms

CA integration issues may present as:

• Certificate requests stuck at CSR Pending

• Issuance failures during provisioning

• Connector status showing errors or inactive

• Authentication failures when testing connector

• Template not visible during ordering

• Revocation requests not propagating

Step 1: Verify Connector Status

Navigate to: Integrations → CA Connectors

Confirm:

• Connector is listed as Active

• Base URL or API endpoint is correct

• No visible validation errors

If the connector is inactive:

• Reactivate from the Actions menu

• Review recent configuration changes

Step 2: Test Endpoint Connectivity

Most CA issues are connectivity-related.

Verify:

• CA API endpoint or Web Enrollment URL is reachable

• Port 443 (HTTPS) is open

• DNS resolution is working

• Proxy settings are correctly configured (if applicable)

For AD CS:

• Test access to https://<ca-server>/certsrv

For API-based connectors:

• Confirm health endpoint access if available

Step 3: Validate Authentication Credentials

Authentication errors commonly occur due to:

• Expired API keys

• Changed service account passwords

• Insufficient enrollment permissions

• Revoked access tokens

Ensure:

• Credentials configured in CERTInext are current

• Service account has enrollment and revocation permissions

• Template-level permissions allow enrollment

Step 4: Verify Template and Policy Mapping

If templates are missing or issuance fails:

Check:

• Template is published at the CA

• Template is enabled for the service account

• Template name matches exactly in CERTInext

• Certificate type (DV/OV/EV or internal profile) is supported

Template mismatch often results in issuance rejection.

Step 5: Review CSR Compatibility

CA rejection may occur if CSR does not meet policy requirements.

Validate:

• Key algorithm and size

• Signature algorithm

• SAN formatting

• Subject field structure

• Required attributes for EV/OV

Ensure CSR profile aligns with CA template policy.

Step 6: Check Revocation Synchronization

If revocation fails:

• Confirm connector credentials allow revocation

• Verify certificate serial number matches CA record

• Check CA audit logs for rejection

Revocation failures may occur if certificate was issued outside CERTInext or under a different account.

Step 7: Review Logs

Check:

• Connector validation logs

• Provisioning bot logs (if issuance triggered via bot)

• Error messages displayed during order submission

Common error categories include:

• 401/403 authentication errors

• Template not found

• Invalid CSR format

• Network timeout

Step 8: Re-test and Retry

After corrections:

• Edit and re-save connector

• Re-initiate certificate order

• Retry provisioning workflow

• Validate updated connector status

When to Escalate

Provide:

• CA Connector Name

• Endpoint URL

• Error message received

• Template name used

• CSR configuration details

• Timestamp of failed attempt

This helps isolate CA-side versus CERTInext-side issues.

Best Practices

• Use dedicated service accounts for each CA connector

• Rotate credentials periodically

• Monitor connector status regularly

• Validate integration after CA upgrades

• Maintain documented template mappings
