Troubleshooting ADExtractor: Common Issues and Fixes
1. Installation fails or installer hangs
- Symptoms: Installer quits with error, hangs at 0–50%, or prerequisites not detected.
- Likely causes: Missing .NET runtime, insufficient permissions, corrupted installer, or blocked by antivirus/Windows SmartScreen.
- Fixes:
- Run as administrator. Right-click installer → Run as administrator.
- Install prerequisites. Ensure required .NET runtime and Visual C++ redistributables are installed.
- Verify installer integrity. Redownload from the official source and compare checksums if available.
- Temporarily disable antivirus/SmartScreen. Re-enable after install.
- Check logs. Review installer logs (typically in %TEMP% or program-specific folder) for specific error codes.
2. Authentication or permission errors when connecting to Active Directory
- Symptoms: “Access denied”, “Invalid credentials”, or partial results returned.
- Likely causes: Account lacks required rights, LDAP/LDAPS binding issues, or network time/kerberos issues.
- Fixes:
- Use an account with appropriate rights. For exports, use an account in Domain Users with read permissions or a delegated service account as documented.
- Verify credentials. Test the account by binding with an LDAP client (e.g., ldapsearch, ADUC).
- Check domain controller reachability. Ping/LDAP port (⁄636) and confirm DNS resolves DC names.
- Confirm Kerberos/time sync. Ensure client and DC clocks are within 5 minutes.
- Try LDAPS if required. If the environment enforces secure binds, use LDAPS and validate certificates.
3. Partial or missing data in exports
- Symptoms: Users, groups, or attributes are missing or truncated.
- Likely causes: Attribute filters, paging limits, schema mismatches, or insufficient read permissions.
- Fixes:
- Check attribute selection. Ensure ADExtractor is configured to request the needed attributes (not a reduced subset).
- Enable paging. If large directories exist, make sure LDAP paging (1,000+ entries) is enabled.
- Validate schema mappings. Confirm custom attributes or extensions are mapped correctly.
- Run with elevated read rights. Some attributes require extra privileges (e.g., msDS-ReplAttributeMetaData).
- Compare with an LDAP query. Use ldapsearch to confirm which entries/attributes are visible with the same account.
4. Slow performance or timeouts
- Symptoms: Exports take excessive time, time out, or consume high CPU/memory.
- Likely causes: Large AD environment, inefficient queries, network latency, or insufficient host resources.
- Fixes:
- Use server-side filters. Narrow queries to only needed objects/containers.
- Enable LDAP paging and indexing. Request results in pages and ensure AD attributes used in filters are indexed.
- Increase timeouts and retry settings. Adjust client timeouts for slow networks.
- Scale resources. Run ADExtractor on a machine with more CPU/RAM or closer network proximity to DCs.
- Schedule off-peak runs. Export during low-usage windows.
5. SSL/Certificate errors with LDAPS
- Symptoms: “Certificate not trusted”, handshake failures, or refusal to connect on 636.
- Likely causes: Self-signed or expired certs on DCs, missing root CA on client, or hostname mismatch.
- Fixes:
- Validate DC certificate. Confirm certificate is valid, trusted, and matches the DC hostname.
- Import root/intermediate CA. Install the CA chain in the client’s Trusted Root store.
- Use correct server name. Use the subject/subjectAltName hostname in the connection.
- Rotate expired certs. Renew certificates on the domain controllers.
6. Incorrect formatting or encoding in output files
- Symptoms: CSV/JSON contains garbled characters, wrong date formats, or broken CSV columns.
- Likely causes: Character encoding mismatches (UTF-8 vs. UTF-16), locale/date format differences, or delimiter collisions.
- Fixes:
- Select UTF-8 with BOM or proper encoding. Match the target system’s expected encoding.
- Specify date/time format. Use ISO 8601 (YYYY-MM-DDTHH:MM:SS) for portability.
- Escape delimiters. Use quoting or a different delimiter if attributes contain commas.
- Validate with sample export. Open in a text editor to confirm format before large runs.
7. Licensing or activation problems
- Symptoms: Feature-limited mode, license errors, or inability to activate.
- Likely causes: Incorrect license key, network activation blocked, or clock skew.
- Fixes:
- Confirm license key and entitlement. Verify product key matches edition.
- Allow activation traffic. Ensure outbound activation URLs are reachable or use offline activation if provided.
- Check system time. Correct clock skew that can invalidate time-limited licenses.
- Contact vendor support with license file and activation logs.
8. Logs show cryptic errors or crashes
- Symptoms: Unexpected exits, stack traces, or repeated error codes in logs.
- Likely causes: Unhandled exceptions, corrupted configuration, or environmental incompatibilities.
- Fixes:
- Collect logs and configs. Gather application logs, event viewer entries, and config files.
- Search known error codes. Consult product knowledge base for matching errors.
- Reset to default config. Temporarily restore defaults to isolate config issues.
- Reproduce with debug mode. Enable verbose/debug logging and rerun the operation.
- Report to vendor with collected artifacts for deeper analysis.
Quick troubleshooting checklist
| Item | Action |
|---|---|
| Connectivity | Ping DCs, test LDAP/LDAPS ports (⁄636) |
| Credentials | Verify account rights and test with ldap tools |
| Paging & Filters | Enable paging, narrow queries, confirm indexed attrs |
| Certificates | Validate chain and hostname for LDAPS |
| Encoding | Use UTF-8 and ISO 8601 dates for exports |
| Logs | Collect app logs and increase verbosity for repro |
