If you read the release notes for 4.5.0, you will find this:

NTLMv1 authentication disabled by default

In order to improve security we have changed
the default value for the "ntlm auth" option from
"yes" to "no". This may have impact on very old
clients which doesn't support NTLMv2 yet.

The primary user of NTLMv1 is MSCHAPv2 for VPNs and 802.1x.

By default, Samba will only allow NTLMv2 via NTLMSSP now,
as we have the following default "lanman auth = no",
"ntlm auth = no" and "raw NTLMv2 auth = no".

If you must use the insecure 'ntlm', I am sure you can work out from
the above what you must add to smb.conf

Personally, I think freeradius need to up their game, I found this on
their wiki, under the heading 'guide/FreeRADIUS Active Directory
Integration HOWTO'

The following components are required to install the access control solution:

    A Linux/Unix server (only Linux is covered)
    FreeRADIUS 3.0.x
    Samba 3.0.x
    Cisco Catalyst Switch
    Windows >= Win2K SP4 XP

As anbody told freeradius that the Samba 3.0.x series went EOL in 2009 ?
and that Win2K & XP are also EOL ?

And people complain about the Samba wiki LOL
