freeradius 3.0.4 CentOS 7.2 AD

[Hubert Kupper]

Hello,

we have freeradius 3.0.4 on a centos 7.2 machine with ldap 
authentication against edirectory running for a long time. Now we want 
to authenticate against AD. We followed the intructions on 
http://deployingradius.com/documents/configuration/active_directory.html

ntlm_auth returns: NT_STATUS_OK: Success (0x0). Radiusd -X returns the 
following error:

/etc/raddb/mods-config/files/authorize[1]: Parse error (check) for entry 
DEFAULT: Unknown value 'ntlm_auth' for attribute 'Auth-Type'

What is the reason?

Regards, Hubert
