Hostname Authentication Failing

Hostname authentication requires a couple of prerequisites to work correctly. If these are not in place, you may see the Captive Portal or your captures may show the IP address as the username upon a hostname authentication failure.

For hostname authentication to work correctly, the following needs to be in place.

• MAC Randomisation disabled in the MDM settings

• Private Wi-Fi disabled on the iPad’s

• A Reverse DNS lookup zone

If the hostname still fails with the above in place, then please contact the support team for further investigation.
