OK, after some initial configuration trouble I have now tried letting FreeRADIUS read a smbpasswd file instead of using ntlm_auth, and now my Windows XP client can successfully authenticate!
So, either there's something fishy inside FreeRADIUS concering the use of ntlm_auth or I guess Samba/ntlm_auth returns returns a broken response. If there's anything I can do to help diagnose and fix this, like provide more logfiles, testing patches or anything else, I'd be happy to help out. Anyway, for now I can solve my authentication needs by running FreeRADIUS on the same server as my Samba domain controller.
