The issue is that the self same configuration in FreeRADIUS 2.0.2 works! But
with 2.1.8 it fails.
The difference in the debug output is:
++[logintime] returns noop
rlm_pap: WARNING! No "known good" password found for the user. Authentication
may fail because of this.
++[pap] returns noop
rad_check_password: Found Auth-Type ldap
auth: type "LDAP"
+- entering group LDAP
rlm_ldap: - authenticate
In FR 2.0.2 this "rad_check_password" is causing LDAP authentication, whereas
is FR 2.1.8 the same section of debug output says:
++[logintime] returns noop
[pap] WARNING! No "known good" password found for the user. Authentication may
fail because of this.
++[pap] returns noop
No authenticate method (Auth-Type) configuration found for the request:
Rejecting the user
Failed to authenticate the user.

True. My problem was why was LDAP not being attempted for this basic request.
No EAP, just a username and a password, which works just fine with FR 2.0.2.
In fact with 2.0.2 either:
if (!EAP-Message) {
ldap
}
or
ldap
Works in the authorise section as the Non-EAP request calls ldap either way.
With FR 2.1.8, both fail. They follow the same path and produce the "No
authentication method ..." error.
All the complex EAP/TTLS/PEAP/MSCHAP etc stuff is working with FR 2.1.8 with my
config, just the simple stuff is broken.
Maybe my question should have been:
"FR 2.0.2 reports 'rad_check_password: Found Auth-Type ldap' then goes on to
authenticate a user against LDAP, whereas FR 2.1.8 reports that there is no
Auth-Type set and does not attempt LDAP authentication."
Complete output for working one:
