Radius with LDAP only without EAP

[snowyrain]

Hello,

I have a pfsense 2.3.2 machine with the radius package.  Login and group membership works, but only without EAP. I have to set the option:
LDAP Authentication Support: Enable LDAP For Authentication: on
Description: “check plain-text password against the ldap database"

Without EAP many wlan-devices make Problems. The LDAP-Server is “paedml based on UCS@school”. When I browse the ldap with an ldap-browser, I don’t see password hashes in the ldap-tree. Maybe this is the fault?

My test results:

Login with plaintext Passwort works:

Command:
	radtest LdapTestUser test12345 10.0.0.2 1812 RadiusSecret
Output:

How can I get authentication with EAP running?

Thank you.
