Does it work also
ntlm_auth --request-nt-key --domain=auth.chrjsn.se --username=adtest
In mods-enabled/mschap
ntlm_auth = "/usr/bin/ntlm_auth --request-nt-key --username=%{%{Stripped-User-Name}:-%{%{User-Name}:-None}} --challenge=%{%{mschap:Challenge}:-00} --nt-response=%{%{mschap:NT-Response}:-00}"
use_mppe = yes
require_encryption = yes
require_strong = yes
authtype = MS-CHAP
with_ntdomain_hack = yes
I think you've also test
kinit adtest
and do
net ads join -U administrator
and nmb winbind and smb are all running
and dns resolve auth.chrjsn.se
