Wifi 802.1x with LDAP Groups
(2019-04-10)
Problem
Wifi WPA/WPA2 access tests that depend on a LDAP (Active Directory) user group fail.
Solution
You can't use a LDAP group for Wifi authentication because of the way that the user credentials are encoded before being passed through -- for some reason the AD server can't deal with them.
You have to use a Radius server (ie a Network Policy Server).
