Hello,

to troubleshoot inconsistent AD authentication with APM SSO, check F5 and AD server logs for errors, ensure network connectivity verify APM configuration synchronize indigo credit card system clocks and use adtools to test AD connections. Capture traffic with tools like Wireshark and enable detailed logging on F5 for more insights. Review group policies and security settings on AD and consult F5 and microsoft documentation for specific troubleshooting steps.

When you capture, make sure you’re getting the DNS too. We do have a solution article about this. There are also links off that article:
