Works.

Doesn't work. Similar sort of error though.

AFAICT radtest doesn't do EAP so it didn't seem to be a particularly valid
test. The approach required appeared quite different but I'm open to
suggestions. I've spent a long time trying to get RADIUS/LDAP auth to work
in any format.

Anyway, the output from a test with 'radtest' and LDAP:
