🔍 Troubleshooting

✅ Recent Fixes (v0.1.0)

LDAP3 Compatibility: Fixed TLS configuration compatibility with latest ldap3 library
Test Suite: All 43 tests now passing successfully (100% success rate)
Mock Issues: Resolved integration test mocking for error scenarios
Security Config: Removed deprecated LDAP parameters for better compatibility

Common Issues

LDAP Connection Failed

# Test connectivity
ldapsearch -H ldap://dc.example.com -D "CN=user,DC=example,DC=com" -W -b "DC=example,DC=com" "(objectClass=domain)"

Permission Denied
- Verify service account permissions
- Check OU access rights
- Ensure proper LDAP bind DN

SSL/TLS Issues

# Test SSL connection
openssl s_client -connect dc.example.com:636 -showcerts

Port Already in Use

# Check port usage
netstat -tlnp | grep 8813
# Change port if needed
HTTP_PORT=8814 ./start_http_server.sh
