Diagnostic report for Cubic Card Terminal LDAP authentication issues. Includes troubleshooting, safety warnings, and preventative maintenance for commercial kiosks.
To be determined by system administrator.
Typically port 389 or 636. Verify with the system administrator.
Consult the network administrator to determine firewall rules.
LDAP (Lightweight Directory Access Protocol) authentication relies on network communication between the card terminal and the LDAP server. The terminal sends authentication requests over a network connection (typically Ethernet or Wi-Fi) using TCP/IP. Voltage fluctuations, network latency, or incorrect TCP configurations will disrupt the transmission and cause authentication failures. The system relies on specific DNS resolution and port accessibility (usually port 389 or 636 for SSL) to establish a secure connection. Environmental factors (-40C) can negatively affect crystal oscillator stability and network IC performance, increasing error rates.
Ensure the card terminal is disconnected from the power source prior to performing any cable inspections or cleaning to prevent electrical shock. Extreme cold can cause materials to become brittle; handle cables and connectors with extra care. Avoid using excessive force when connecting or disconnecting cables.
Regularly inspect and clean network cables and connectors. Ensure cables are properly secured to prevent strain. Monitor network performance for latency or packet loss. Schedule routine maintenance checks of the LDAP server.
Use a network packet sniffer (e.g., Wireshark) to capture and analyze network traffic between the terminal and the LDAP server. This can help identify connectivity issues or incorrect protocol exchanges. Verify the terminal's system time is synchronized with a reliable NTP server. Time discrepancies can cause authentication failures.
